From 432c4ec85f95a88338d3ae9c2d06f5b6ecb83818 Mon Sep 17 00:00:00 2001 From: Leonardo Saturnino Date: Wed, 5 Nov 2025 00:00:29 -0500 Subject: [PATCH 01/15] feat(sdk): add gasless deposit type exports and comprehensive test coverage Implements SDK type exports and test infrastructure for gasless tBTC deposits feature, where relayer backend pays all gas fees for deposit reveals. Type System: - Export GaslessDepositResult interface for deposit initialization results - Export GaslessRevealPayload interface for backend relay submission - Add type export validation tests to prevent regressions Test Coverage: - Add comprehensive unit tests for initiateGaslessDeposit (L1 and L2 paths) - Add comprehensive unit tests for buildGaslessRelayPayload (owner encoding) - Verify error handling for unsupported chains and uninitialized contracts - Validate Bitcoin recovery address formats (P2PKH, P2WPKH) - Test chain-specific owner encoding (bytes32 for L1, address for L2) Documentation: - Add JSDoc documentation to gasless deposit helper methods - Document depositKey computation happens on backend (Bitcoin hash256) - Document chain-specific owner encoding requirements Code Quality: - Remove unused test variables - Fix all linting errors - Ensure all 683 tests pass with zero regressions This implementation ensures proper Bitcoin hash256 usage and chain-specific encoding for gasless deposit functionality. --- typescript/api-reference/README.md | 58 +- .../api-reference/classes/DepositsService.md | 286 +++++- .../interfaces/GaslessDepositResult.md | 60 ++ .../interfaces/GaslessRevealPayload.md | 98 ++ typescript/package.json | 6 +- typescript/src/lib/ethereum/constants.ts | 41 + typescript/src/lib/ethereum/index.ts | 1 + .../src/lib/solana/solana-tbtc-token.ts | 1 + .../src/services/deposits/deposits-service.ts | 424 +++++++- typescript/test/exports/gasless-types.test.ts | 151 +++ .../test/lib/ethereum/constants.test.ts | 86 ++ typescript/test/services/deposits.test.ts | 921 +++++++++++++++++- typescript/yarn.lock | 228 +++-- 13 files changed, 2275 insertions(+), 86 deletions(-) create mode 100644 typescript/api-reference/interfaces/GaslessDepositResult.md create mode 100644 typescript/api-reference/interfaces/GaslessRevealPayload.md create mode 100644 typescript/src/lib/ethereum/constants.ts create mode 100644 typescript/test/exports/gasless-types.test.ts create mode 100644 typescript/test/lib/ethereum/constants.test.ts diff --git a/typescript/api-reference/README.md b/typescript/api-reference/README.md index bc80392c4..c66204106 100644 --- a/typescript/api-reference/README.md +++ b/typescript/api-reference/README.md @@ -77,6 +77,8 @@ - [ElectrumCredentials](interfaces/ElectrumCredentials.md) - [EthereumContractConfig](interfaces/EthereumContractConfig.md) - [ExtraDataEncoder](interfaces/ExtraDataEncoder.md) +- [GaslessDepositResult](interfaces/GaslessDepositResult.md) +- [GaslessRevealPayload](interfaces/GaslessRevealPayload.md) - [L1BitcoinRedeemer](interfaces/L1BitcoinRedeemer.md) - [L2BitcoinRedeemer](interfaces/L2BitcoinRedeemer.md) - [RedeemerProxy](interfaces/RedeemerProxy.md) @@ -145,6 +147,7 @@ - [BitcoinTargetConverter](README.md#bitcointargetconverter) - [ChainMappings](README.md#chainmappings) - [EthereumCrossChainExtraDataEncoder](README.md#ethereumcrosschainextradataencoder) +- [NATIVE\_BTC\_DEPOSITOR\_ADDRESSES](README.md#native_btc_depositor_addresses) - [SolanaCrossChainExtraDataEncoder](README.md#solanacrosschainextradataencoder) - [StarkNetCrossChainExtraDataEncoder](README.md#starknetcrosschainextradataencoder) - [StarkNetDepositor](README.md#starknetdepositor) @@ -413,7 +416,7 @@ or a Provider that works only in the read-only mode. #### Defined in -[lib/ethereum/index.ts:35](https://github.com/threshold-network/tbtc-v2/blob/main/typescript/src/lib/ethereum/index.ts#L35) +[lib/ethereum/index.ts:36](https://github.com/threshold-network/tbtc-v2/blob/main/typescript/src/lib/ethereum/index.ts#L36) ___ @@ -968,6 +971,51 @@ Use EthereumExtraDataEncoder instead ___ +### NATIVE\_BTC\_DEPOSITOR\_ADDRESSES + +• `Const` **NATIVE\_BTC\_DEPOSITOR\_ADDRESSES**: `Record`\<[`Mainnet`](enums/BitcoinNetwork-1.md#mainnet) \| [`Testnet`](enums/BitcoinNetwork-1.md#testnet), `string`\> + +NativeBTCDepositor contract addresses for gasless L1 tBTC deposits. + +These contracts enable users to make Bitcoin deposits to L1 Ethereum +without paying gas fees.

chain validation and normalization Add chain validation and backend-compatible chain name normalization for gasless tBTC deposits to improve error handling and ensure seamless backend integration. Changes: - Update testnet NativeBTCDepositor address to deployed Sepolia contract - Add SUPPORTED_GASLESS_CHAINS constant to validate deposit chains early - Implement chain name normalization in buildGaslessRelayPayload (SDK accepts capitalized names, backend receives lowercase) - Enhance JSDoc documentation with supported chains and capitalization - Add comprehensive test coverage for validation and normalization Technical details: - Supported chains: L1, Arbitrum, Base, Sui, StarkNet - Solana excluded due to different architecture - Chain names normalized to lowercase except "L1" - Early validation prevents runtime errors with clear messages Test results: 55 passing, 0 failing --- .../api-reference/classes/DepositsService.md | 82 +++++++---- .../interfaces/GaslessRevealPayload.md | 7 +- typescript/src/lib/ethereum/constants.ts | 2 +- .../src/services/deposits/deposits-service.ts | 74 ++++++++-- typescript/test/services/deposits.test.ts | 132 +++++++++++++++++- 5 files changed, 246 insertions(+), 51 deletions(-) diff --git a/typescript/api-reference/classes/DepositsService.md b/typescript/api-reference/classes/DepositsService.md index 9d5fa7c60..f211c2664 100644 --- a/typescript/api-reference/classes/DepositsService.md +++ b/typescript/api-reference/classes/DepositsService.md @@ -16,6 +16,7 @@ Service exposing features related to tBTC v2 deposits. -
