How to Compare Bridge Costs on Sui
A checklist for comparing quotes, gas, destination fees, and expected received amounts.
Why this matters on Sui
A proper fee comparison uses the final received amount rather than the headline bridge fee. Gas and price impact can materially change the result.
Sui uses an object-centric model that differs from the account and token conventions of EVM networks.
Sui does not follow standard EVM conventions. Address formats, token identifiers and approval mechanics differ, so EVM-oriented checklists and tools should only be applied to Sui after confirming they are supported.
Sui: what to pay attention to
- Costs: Consider network transaction costs and route-specific costs when evaluating small balances.
- Security: Review transaction effects carefully and use trusted wallet interfaces.
- Assets and tokens: Verify the network-specific asset and object details rather than applying EVM assumptions.
A Sui checklist for this topic
- Allow for a delay between sending and receiving; do not repeat a transfer while one is pending.
- Keep enough native balance on Sui to pay for the transaction that starts the transfer.
- Review the final recipient address and network before confirming a cross-chain transfer.
- Confirm both the source and destination network, including whether Sui is one of them.
