From 747f86ea3ac8afeaf5e5bb407829f2bc72bbe0f8 Mon Sep 17 00:00:00 2001 From: Andrey Kobrin Date: Fri, 3 Apr 2026 18:13:39 -0400 Subject: [PATCH 01/26] feat: add EVM migration support and refactor tx building pipeline - Add EVMigration module client with query operations (Params, MigrationRecord, MigrationRecordByNewAddress, MigrationEstimate, MigrationStats) and wire it into blockchain.Client - Refactor tx building into composable stages: - PrepareTx: builds unsigned tx builder and resolves signer metadata - SignPreparedTx: signs a prepared builder with explicit signer info - BuildAndSignTxWithOptions: end-to-end build+sign with TxBuildOptions - BroadcastAndWait: broadcast + wait-for-inclusion convenience method - Support explicit AccountNumber/Sequence, GasLimit, SkipSimulation, FeeAmount, and multi-message transactions via TxBuildOptions - Replace local ethsecp256k1 implementation with cosmos/evm upstream (github.com/cosmos/evm/crypto/ethsecp256k1), removing pkg/crypto/ethsecp256k1/ package - Register additional module interfaces in NewDefaultTxConfig (bank, staking, distribution, authz, claim, supernode) for proper tx encoding/decoding - Bump dependencies: - Go 1.25.5 -> 1.26.1 - cosmos-sdk v0.53.5 -> v0.53.6 - cometbft v0.38.20 -> v0.38.21 - grpc v1.77.0 -> v1.79.2 - LumeraProtocol/lumera v1.10.0 -> v1.11.0 - Add github.com/cosmos/evm v0.6.0 - Add comprehensive tests for tx building (manual signer info, queried account info + simulation, default message sizes) - Apply config defaults (MaxRecvMsgSize/MaxSendMsgSize) in base.New - Remove deprecated blockchain/messages.go - Update docs and copilot-instructions for Go 1.26.1 --- .github/copilot-instructions.md | 2 +- blockchain/base/client.go | 19 +- blockchain/base/tx.go | 259

feat: add evmigration tx helpers and EVM address helper - Register evmigration interfaces in the default tx config so MsgClaimLegacyAccount / MsgMigrateValidator can be encoded and signed. - Add ClaimLegacyAccountTx / MigrateValidatorTx helpers plus NewMsgClaimLegacyAccount / NewMsgMigrateValidator constructors and MigrationResult on EVMigrationClient. - Add EVMAddressFromKey to derive a 0x EIP-55 address for eth_secp256k1 keys; promote go-ethereum to a direct dependency. --- blockchain/evmigration.go | 82 +++++++++++++++++++++++++++++++++++++++ go.mod | 2 +- pkg/crypto/address.go | 30

EthCall/EstimateGas marshal TransactionArgs JSON for the cosmos/evm gRPC contract. - FeeMarketClient (x/feemarket): Params, BaseFee (ulume decimal), BlockGas. Companion to EVMClient.BaseFee which returns alume. - PreciseBankClient (x/precisebank): Remainder, FractionalBalance. - All three wired onto blockchain.Client via the existing constructor. Tests stub the QueryClient interface directly instead of going through bufconn, because the default grpc proto v2 codec panics on gogoproto customtype fields (sdkmath.Int / LegacyDec) in EVM responses. Tests cover Lumera-flavored defaults (BaseFee 0.0025 ulume/gas, etc).

Configuration additions plumbed end-to-end: - blockchain/base/Config gains EVMChainID, EVMNativeDenom (ulume), EVMExtendedDenom (alume), EVMGasTipCap, EVMGasFeeCap. - client/config mirrors them; client.WithEVMChainID / WithEVMNativeDenom / WithEVMExtendedDenom / WithEVMGasCaps expose them via Option. - client.New copies the EVM fields into blockchain.Config. Guards: - validateTxBuildOptions rejects MsgEthereumTx in the cosmos signing pipeline so callers cannot accidentally double-sign. - SendEthereumTransaction / RawEthereumTx error when EVMClient lacks a Client backref or EVMChainID is unset. Tests cover envelope round-trip via the standard TxDecoder, the CREATE address derivation, and the new guards.

Plus RegisterERC20Tx and ToggleConversionTx for governance flows. All four use the standard cosmos signing pipeline (BuildAndSignTx) โ€” no Ethereum signing. - ConversionResult result type and broadcastConversion shared helper. - ABI sugar (erc20_abi.go): hand-rolled minimal ERC20 JSON (balanceOf, totalSupply, allowance, name, symbol, decimals) compiled at init. Erc20Balance / Erc20TotalSupply / Erc20Allowance / Erc20Metadata pack calldata and route through EVMClient.CallContract. Tests cover queries, message constructors, and ABI pack/unpack.

feat(evm): Phase 5 Lumera precompile wrappers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - pkg/evm/precompiles exposes vendored Hardhat artifact ABIs (action, supernode, wasm) via go:embed and parses them at init. Also exports Lumera custom precompile addresses (0x0901 / 0x0902 / 0x0903) and the eight standard cosmos/evm precompile addresses as named constants. Generic PackCall / UnpackReturn helpers wrap the go-ethereum abi package. - blockchain.PrecompileClient: a single generic wrapper that holds a precompile address + parsed ABI and routes calls through EVMClient. Call(ctx, method, args...) does a read-only EthCall and unpacks the outputs; Send(ctx, method, opts, args...) signs and broadcasts a state-changing call via SendEthereumTransaction. - EVMClient grows Action / Supernode / Wasm fields wired at construction to the corresponding precompile addresses + ABIs. Callers invoke any method on any precompile without compiling Solidity bindings. ABI artifacts are Hardhat-format JSON with an `abi` field; the loader falls back to a bare array if a vendor switches formats later. Tests verify the embedded ABIs parse, exposed method names match the docs, and the PrecompileClient guards against missing backref / unknown method. Phase 5 of docs/design/0001-cosmos-evm-api.md. Typed wrappers for specific methods (RequestCascade, RegisterSupernode, etc.) are out of scope for v1 โ€” callers compose them with PackCall and the published ABI. --- blockchain/client.go | 10 + blockchain/evm.go | 5 + blockchain/precompiles.go | 58 ++ blockchain/precompiles_test.go | 39 ++ pkg/evm/precompiles/abi/action.json | 706 +++++++++++++++++++++++ pkg/evm/precompiles/abi/supernode.json | 725 ++++++++++++++++++++++++ pkg/evm/precompiles/abi/wasm.json | 142 +++++ pkg/evm/precompiles/precompiles.go | 107 ++++ pkg/evm/precompiles/precompiles_test.go | 56 ++ 9 files changed, 1848 insertions(+) create mode 100644 blockchain/precompiles.go create mode 100644 blockchain/precompiles_test.go create mode 100644 pkg/evm/precompiles/abi/action.json create mode 100644 pkg/evm/precompiles/abi/supernode.json create mode 100644 pkg/evm/precompiles/abi/wasm.json create mode 100644 pkg/evm/precompiles/precompiles.go create mode 100644 pkg/evm/precompiles/precompiles_test.go diff --git a/blockchain/client.go b/blockchain/client.go index fc3b2c7..ac27c17 100644 --- a/blockchain/client.go +++ b/blockchain/client.go @@ -14,10 +14,13 @@ import ( claimtypes "github.com/LumeraProtocol/lumera/x/claim/types" evmigrationtypes "github.com/LumeraProtocol/lumera/x/evmigration/types" supernodetypes "github.com/LumeraProtocol/lumera/x/supernode/v1/types" + "github.com/LumeraProtocol/sdk-go/pkg/evm/precompiles" erc20types "github.com/cosmos/evm/x/erc20/types" feemarkettypes "github.com/cosmos/evm/x/feemarket/types" precisebanktypes "github.com/cosmos/evm/x/precisebank/types" evmtypes "github.com/cosmos/evm/x/vm/types" + "github.com/ethereum/go-ethereum/accounts/abi" + "github.com/ethereum/go-ethereum/common" ) // Config mirrors the base blockchain config for Lumera-specific usage. @@ -91,5 +94,12 @@ func New(ctx context.Context, cfg Config, kr keyring.Keyring, keyName string) (* } c.EVM.client = c c.ERC20.client = c + c.EVM.Action = newPrecompileClient(c.EVM, precompiles.ActionAddress, precompiles.ActionABI) + c.EVM.Supernode = newPrecompileClient(c.EVM, precompiles.SupernodeAddress, precompiles.SupernodeABI) + c.EVM.Wasm = newPrecompileClient(c.EVM, precompiles.WasmAddress, precompiles.WasmABI) return c, nil } + +func newPrecompileClient(evm *EVMClient, addr common.Address, parsed abi.ABI) *PrecompileClient { + return &PrecompileClient{address: addr, abi: parsed, evm: evm} +} diff --git a/blockchain/evm.go b/blockchain/evm.go index f9acebb..fa861ad 100644 --- a/blockchain/evm.go +++ b/blockchain/evm.go @@ -23,6 +23,11 @@ import ( type EVMClient struct { query evmtypes.QueryClient client *Client // backref for tx helpers (nil for query-only tests) + + // Lumera precompile wrappers.

Eliminates the race in the old post-broadcast EthAccount.Nonce-1 path. - resolveEVMDenoms: fall back to querying x/vm Params for native and extended denoms when Config leaves them empty. - resolveMinGasTipCap: pull the default tip cap from feemarket.Params.MinGasPrice (ulume decimal) and scale to alume via ULumeDecToWei, instead of GlobalMinGasPrice. - buildEthereumTxBytes: require a non-empty extended denom; falling back to the native denom silently produced wrong-denom fees. - Tighten ABI tests: wasm.execute is phase-1 non-payable, supernode.registerSupernode keeps bech32 string args, action fees stay uint256. Plus tests for the new gas-cap and denom-fallback paths. - Docstring polish in base/Config and ethsign.WrapAsMsgEthereumTx. --- blockchain/base/config.go | 5 +- blockchain/evm.go | 112 ++++++++++++++++++------ blockchain/evm_test.go | 61 +++++++++++++ blockchain/evm_tx_test.go | 27 +++++- pkg/crypto/ethsign.go | 2 +- pkg/evm/precompiles/precompiles_test.go | 27 ++++++ 6 files changed, 199 insertions(+), 35 deletions(-) diff --git a/blockchain/base/config.go b/blockchain/base/config.go index d068d16..aca0f50 100644 --- a/blockchain/base/config.go +++ b/blockchain/base/config.go @@ -28,8 +28,9 @@ type Config struct { EVMChainID *big.Int // EVMNativeDenom is the cosmos/evm `evm_denom` parameter โ€” the bank denom - // fees are deducted in (Lumera: "ulume").

Use the query helpers for pre-flight checks, then submit a migration tx signed by the new address. - -```go -// Pre-flight: confirm the migration would succeed and inspect what is touched. -est, err := lumera.Blockchain.EVMigration.MigrationEstimate(ctx, legacyAddr) -if err != nil { log.Fatal(err) } -if !est.WouldSucceed { - log.Fatalf("cannot migrate: %s", est.RejectionReason) -} - -// Build proofs (legacy + new key) externally, then submit: -msg := blockchain.NewMsgClaimLegacyAccount(newAddr, legacyAddr, legacyProof, newProof) -res, err := lumera.Blockchain.ClaimLegacyAccountTx(ctx, msg, "migrate") -if err != nil { log.Fatal(err) } -log.Printf("migrated legacy=%s new=%s tx=%s height=%d", res.LegacyAddress, res.NewAddress, res.TxHash, res.Height) - -// Validators use MigrateValidatorTx instead: -vmsg := blockchain.NewMsgMigrateValidator(newAddr, legacyAddr, legacyProof, newProof) -_, err = lumera.Blockchain.MigrateValidatorTx(ctx, vmsg, "") -``` - -Read-only helpers: `MigrationRecord(legacyAddress)`, `MigrationRecordByNewAddress(newAddress)`, `MigrationStats(ctx)`, and `Params(ctx)`. `MigrationProof` construction is chain-specific and out of scope here โ€” see the `x/evmigration` proto definitions for the required fields. - -### 8) Send an Ethereum-format transaction - -Lumera accepts EIP-1559 transactions signed in Ethereum format and wrapped as `MsgEthereumTx`. The SDK handles nonce, gas, fee, signing, and broadcast end-to-end. - -```go -// Configure the client with the EVM chain ID and Lumera's precisebank denoms. -lumera, err := client.New(ctx, cfg, kr, - client.WithKeyName("alice"), // eth_secp256k1 key - client.WithEVMChainID(big.NewInt(1414)), // EIP-155 chain ID - client.WithEVMNativeDenom("ulume"), - client.WithEVMExtendedDenom("alume"), -) - -to := common.HexToAddress("0x000000000000000000000000000000000000dEaD") -amount := sdkcrypto.Wei(sdkmath.NewInt(1)) // 1 ulume = 10^12 alume - -res, err := lumera.Blockchain.EVM.SendEthereumTransaction(ctx, &to, nil, &blockchain.EthereumTxOptions{ - Value: amount, -}) -if err != nil { log.Fatal(err) } -log.Printf("eth tx %s cosmos tx %s height %d gas %d", - res.EthTxHash.Hex(), res.CosmosHash, res.Height, res.GasUsed) -``` - -Other helpers on `Blockchain.EVM`: - -- `CallContract(ctx, to, calldata)` for read-only ABI calls. -- `DeployContract(ctx, bytecode, opts)` for contract creation (returns the deployed address). -- `RawEthereumTx(ctx, signedTx)` for callers that sign elsewhere (hardware wallet, MetaMask). - -Nonce is shared with the cosmos auth sequence on Lumera โ€” mixing `SendEthereumTransaction` and `BuildAndSignTx` for the same key needs no coordination, but a stale cached nonce will. The SDK currently does not cache nonces (per-call lookup against `EthAccount`). - -### 9) ERC20 conversion - -Wrap a cosmos coin as an ERC20 token, or unwrap back: - -```go -// ulume -> ERC20 representation for the EVM address. -coin := sdk.NewInt64Coin("ulume", 1_000_000) -recv := common.HexToAddress("0xAbC...") -res, err := lumera.Blockchain.ConvertCoinToERC20(ctx, coin, recv, "") - -// ERC20 balance via the standard ABI helpers (no Solidity compilation needed). -contract := common.HexToAddress("0xCafe...") -holder := common.HexToAddress("0xBeef...") -bal, err := lumera.Blockchain.ERC20.Erc20Balance(ctx, contract, holder) -``` - -### 10) Invoke a Lumera precompile - -Custom precompiles at `0x0901` (action), `0x0902` (supernode), and `0x0903` (wasm) are wrapped by `EVMClient.Action / Supernode / Wasm`. Each exposes a generic `Call` (read) and `Send` (state-changing) that pack calldata via the embedded ABI: - -```go -// Read: get the action module params from the EVM side. -out, err := lumera.Blockchain.EVM.Action.Call(ctx, "getParams") - -// Write: approve an action via the precompile, signed with an eth_secp256k1 key. -_, err = lumera.Blockchain.EVM.Action.Send(ctx, "approveAction", nil, "action-id-here") -``` - -The published ABI is in `pkg/evm/precompiles/abi/`. For typed wrappers around specific methods, compose `precompiles.PackCall` with your own struct definitions or import them from `cosmos/evm`. - -### 11) Manage SuperNodes - -Registration/updates use `lumera.Blockchain.SuperNode` transaction helpers: - -```go -_, err := lumera.Blockchain.RegisterSupernodeTx(ctx, cfg.Address, "lumeravaloper...", "1.2.3.4", "lumera1sn...", "26656", "") -if err != nil { log.Fatal(err) } -``` - -Query helpers include `GetSuperNode`, `ListSuperNodes`, and `GetTopSuperNodesForBlock`. - -## ICA Controller Overview - -The `ica` package provides a production-ready ICA (Interchain Accounts / ICS-27) controller that manages the full lifecycle of cross-chain message execution against Lumera. - -### What it does - -`ica.Controller` connects to both a controller chain and the Lumera host chain over gRPC. It handles ICA registration, IBC packet construction, transaction broadcasting, acknowledgement polling, and action ID extraction โ€” all behind a small set of methods: - -```go -ctrl, _ := ica.NewController(ctx, ica.Config{ - Controller: controllerBaseConfig, - Host: hostBaseConfig, - Keyring: kr, - KeyName: "controller-key", - HostKeyName: "host-key", // optional: separate key for host chain - ConnectionID: "connection-0", -}) -defer ctrl.Close() - -addr, _ := ctrl.EnsureICAAddress(ctx) // register + poll until ready -result, _ := ctrl.SendRequestAction(ctx, msg) // send, wait for ack, return action ID -txHash, _ := ctrl.SendApproveAction(ctx, approveMsg) -``` - -For lower-level or offline workflows, packet-building helpers are available separately: `PackRequestAny`, `BuildICAPacketData`, `BuildMsgSendTx`. - -### Strengths - -- **Minimal setup** โ€” only gRPC endpoints, a keyring, and an IBC connection ID are required. No Docker, no relayer binary, no chain binaries. -- **End-to-end in one call** โ€” `SendRequestAction` builds the ICA packet, broadcasts on the controller chain, waits for tx inclusion, resolves the counterparty channel, polls for the host-chain acknowledgement, and extracts the action ID. -- **Mixed key type support** โ€” controller and host chains can use different cryptographic key types (`KeyTypeCosmos` / `KeyTypeEVM`) by setting `HostKeyName` to a separate key in the same keyring. -- **Resilient polling** โ€” configurable retry counts and delays for both ICA registration (`PollRetries` / `PollDelay`) and acknowledgement waiting (`AckRetries`). -- **Tight Lumera integration** โ€” purpose-built for `MsgRequestAction` and `MsgApproveAction`, with typed results (`ActionResult`) and Cascade metadata compatibility. - -### Limitations - -- **Requires running chains** โ€” the controller connects to live gRPC endpoints. It does not spin up chains or relayers; infrastructure must already be deployed. -- **Lumera-specific high-level methods** โ€” `SendRequestAction` and `SendApproveAction` are tailored to Lumera action messages. Generic ICA message execution requires using the lower-level packet helpers directly. -- **No chain lifecycle management** โ€” unlike e2e testing frameworks (e.g., interchaintest), there is no built-in chain provisioning, genesis configuration, or relayer orchestration. -- **Relayer dependency** โ€” IBC packet relay between controller and host chains depends on an external relayer (e.g., Hermes). The controller does not relay packets itself. - -### When to use this vs. interchaintest - -| Aspect | `ica.Controller` | interchaintest | -| --- | --- | --- | -| **Purpose** | Production client / scripting | E2E integration testing | -| **Infrastructure** | Connects to running chains | Spins up chains + relayers in Docker | -| **Setup effort** | Config struct + keyring | Docker, chain binaries, genesis config | -| **Iteration speed** | Fast (gRPC calls) | Slower (container lifecycle + block production) | -| **Scope** | Lumera ICA operations | Any IBC flow, any chain | - -Use `ica.Controller` when you have running chains and need to execute ICA operations in production or automation scripts. Use interchaintest when you need to validate the full ICA flow in CI from scratch without external infrastructure. - -## Examples and testing - -- Run tests: `make test` -- Build samples: `make examples` -- Execute tutorials end-to-end: `go run ./examples/cascade-upload`, `go run ./examples/cascade-download`, `go run ./examples/query-actions`, `go run ./examples/multi-account`, `go run ./examples/ica-request-tx --help` - -## Troubleshooting - -- **Tx inclusion timing out**: adjust `WaitTx` polling/backoff (see `client/config`). Ensure `RPCEndpoint` allows websocket subscriptions. -- **gRPC TLS errors**: remote hosts/port 443 default to TLS; for local nodes use `localhost:9090` or `127.0.0.1:9090`. -- **Key not found**: confirm the key name exists in the keyring path you passed to `keyring.New`. -- **SuperNode availability**: Cascade operations require reachable SuperNodes; watch `sdk:supernodes_unavailable` events for diagnostics. +Run `make examples` to compile them all. diff --git a/docs/guides/actions.md b/docs/guides/actions.md new file mode 100644 index 0000000..04a8168 --- /dev/null +++ b/docs/guides/actions.md @@ -0,0 +1,44 @@ +# Actions and SuperNodes + +Lumera's `x/action` and `x/supernode` modules are exposed off `Client.Blockchain`.

branch audit: - keyring: ImportKey now verifies an existing key was derived from the supplied mnemonic, instead of silently returning the stored key's address when a different mnemonic is imported under the same name. - evm: buildEthereumTxBytes rejects an empty native denom (previously panicked in sdk.NewCoin); resolveEVMDenoms errors are now actionable. - evm: DeployContract returns the zero address + error when the constructor reverts (VmError) instead of an address with no contract. - erc20: balance/supply/allowance/metadata reads return a clear error on empty return data rather than a cryptic ABI unmarshal error. - tx: resolveGasLimit propagates simulation errors instead of silently falling back to a fixed gas limit that can under-gas the tx. - evm: guard GasUsed int64->uint64 cast; feemarket BlockGas rejects negative gas; AddressFromKey guards an empty derived address. - client: forward AccountHRP/FeeDenom/GasPrice from the client config into the blockchain config (With* options added). - wait-tx: surface the subscriber error when the poller also fails. - precompiles: parseHardhatABI handles an explicit null abi field. Adds regression tests for each behavioral change.
