Note

Low Risk
Low risk: this PR only adds static ERC-20 metadata and an SVG asset, with no runtime logic changes.

Token name inconsistent with existing mainnet entry

Low Severity

The name field is "ether.fi BTC" here, but the same contract address on Ethereum mainnet (eip155:1) is registered as "ether.fi Staked BTC" in this repo's existing metadata and in contract-map.json. CoinMarketCap also lists it as "ether.fi Staked BTC." This discrepancy means the same token will display different names depending on the chain, which could confuse users. Worth verifying the on-chain name() return value and aligning both entries.
