Salvages the closed PR #2010 (Mibayy's EVM multi-chain skill) and folds the existing optional-skills/blockchain/base/ skill into it, so we ship one unified EVM skill instead of two overlapping ones. Pulled in from base/: - 8 missing Base-specific tokens (AERO, DEGEN, TOSHI, BRETT, WELL, cbETH, cbBTC, wstETH, rETH) added to KNOWN_TOKENS['base'] — base/ had 11, evm/ only had 3 (USDC/DAI/WETH). - L1 data-fee pitfall note for rollups (Base, Arbitrum, Optimism, zkSync). - Batch-size chunking in rpc_batch (Base RPC caps batches at 10 calls per JSON-RPC request; adding more known tokens tripped that limit and broke 'wallet --chain base' with a 'list index out of range' error). Ported the chunking pattern from base/_rpc_batch_chunk. Latent bugs found and fixed while smoke-testing the merge: - cmd_multichain and cmd_allowance both iterated KNOWN_TOKENS[chain] with 'for contract, (symbol, _name) in known.items()' — but the dict shape is {symbol: contract_str}, not {addr: (sym, name)}. This raised 'too many values to unpack (expected 2)' on every non-zero balance. Now iterates as 'for symbol, contract in known.items()'. - Input validation: added is_valid_address / is_valid_txhash / require_address / require_txhash helpers and wired them into cmd_wallet, cmd_tx, cmd_token, cmd_activity, cmd_allowance, cmd_decode, cmd_contract, cmd_multichain. Fails fast with exit 2 on malformed input instead of burning an RPC round-trip on garbage. Documentation: - SKILL.md now flags that this skill supersedes optional-skills/blockchain/base. - Pitfalls expanded for ENS (single-endpoint dependency on ensideas.com), tx decoding (single-endpoint dependency on 4byte.directory), and rollup L1 fees. - Regenerated website/docs/user-guide/skills/optional/blockchain/ blockchain-evm.md and removed the old blockchain-base.md page; catalog updated. Removed: - optional-skills/blockchain/base/SKILL.md - optional-skills/blockchain/base/scripts/base_client.py - website/docs/user-guide/skills/optional/blockchain/blockchain-base.md Smoke-tested live against Base mainnet: stats, price, token, wallet (vitalik.eth — 3.12 ETH + 13.88 USDC + 4.23 DAI + 0.06 WETH on Base) and allowance (ethereum, 7 unlimited approvals to Uniswap/Permit2).
