Wrapping Tokens

In MiniEVM Rollup, every bridged token is wrapped to 18 decimals, regardless of token or bridge type. This enforces a single decimal format and avoids issues caused by decimal differences. Wrapping is handled by the Wrapper precompile in MiniEVM. Initia bridge handles tokens with 6 decimals, so wrapped tokens with 18 decimals are unwrapped to 6 decimals before they are bridged to L1.

When you bridge 6 decimals token from Initia L1 to an EVM rollup, it is converted into an 18 decimals ERC‑20 token.

Unwrapping tokens is the reverse process, where you convert the 18 decimals ERC-20 token back to the original 6 decimals token on Initia L1.
