 ## Usage
 
-### Loading ABI (ethers / viem / web3, etc.)
-
-```javascript
-import IBankAbi from "cosmos-evm-contracts/abi/precompiles/bank/IBank.json" assert { type: "json" };
-
-// or Node
-const IBankAbi = require("cosmos-evm-contracts/abi/precompiles/bank/IBank.json");
-```

 ### Loading ABI with TypeScript / viem (typed)
 
 Import the named ABI constant so that `functionName`, `args`, and return types are inferred:
