+# ALIGN Token on Base L2
+
+Deployment and bridging of the Aligned Token (ALIGN) on Base using the [OP Standard Bridge](https://docs.optimism.io/app-developers/tutorials/bridging/standard-bridge-standard-token).
+
+## Setup
+
+```bash
+cp .env.example .env
+```
+
+## Deploy
+
+The L2 token is created via the `OptimismMintableERC20Factory` predeploy at `0x4200000000000000000000000000000000000012`. No custom contract is needed.
+
+```bash
+make deploy-base-sepolia   # BaseSepolia
+make deploy-base-mainnet   # BaseMainnet
+```
+
+## Verify
+
+```bash
+make verify L2_TOKEN=<address> RPC_URL=https://sepolia.base.org
+```
+
+## Bridge (L1 -> Base)
+
+Approve + deposit in one command. `AMOUNT` is the token amount with 18 decimals (1000000000000000000 = 1 ALIGN).
+
+```bash
+make bridge-l1-to-base-sepolia AMOUNT=1000000000000000000
+make bridge-l1-to-base-mainnet AMOUNT=1000000000000000000
+```
+
+Tokens appear on Base after ~20 minutes.
+
+To bridge to a different L2 address, use the `TO` parameter:
+
+```bash
+make bridge-l1-to-base-sepolia-to AMOUNT=1000000000000000000 TO=0x...
+make bridge-l1-to-base-mainnet-to AMOUNT=1000000000000000000 TO=0x...
+```
+
+## Withdraw (Base -> L1)
+
+Withdrawals are a [multi-step process](https://docs.optimism.io/app-developers/tutorials/bridging/cross-dom-bridge-erc20#withdraw-tokens). No approval is needed. All three steps use the same `TX_HASH` — the **L2 initiation tx hash** from step 1.
+
+1. **Initiate** on L2 (burns tokens on Base):
+
+   ```bash
+   make withdraw-base-to-l1-sepolia AMOUNT=1000000000000000000
+   make withdraw-base-to-l1-mainnet AMOUNT=1000000000000000000
+   ```
+
+   To withdraw to a different L1 address, use the `TO` parameter:
+
+   ```bash
+   make withdraw-base-to-l1-sepolia-to AMOUNT=1000000000000000000 TO=0x...
+   make withdraw-base-to-l1-mainnet-to AMOUNT=1000000000000000000 TO=0x...
+   ```
+
+   Save the tx hash from this step — it's needed for prove and finalize.
+
+2. **Prove** on L1 — wait ~1 hour for the L2 output to be proposed, then prove:
+
+   ```bash
+   make prove-withdrawal-sepolia TX_HASH=<L2 initiation tx hash>
+   make prove-withdrawal-mainnet TX_HASH=<L2 initiation tx hash>
+   ```
+
+3. **Finalize** on L1 — wait 7 days challenge period (shorter on testnet), then finalize:
+
+   ```bash
+   make finalize-withdrawal-sepolia TX_HASH=<L2 initiation tx hash>
+   make finalize-withdrawal-mainnet TX_HASH=<L2 initiation tx hash>
+   ```
+
+   > **Note:** Prove and finalize use `viem` + `viem/op-stack`. Run `npm install` first.
