Native Token Handling

Tycho uses a specific address convention for native tokens that differs from some protocols.

Address Convention

Tycho reserves the zero address (0x0000000000000000000000000000000000000000) to represent the native token across all chains.

Some protocols use 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE or other sentinel addresses for native tokens. If your protocol follows this pattern, you must normalize these addresses to the zero address in your Substreams package.
