Objective

Enable users to transfer "NTT" tokens between supported chains. Users should have the option to manually execute the transfer (requiring 2 transactions) or use relayers for automatic transfer (requiring 1 transaction). Initially this will only support NTT tokens that use Wormhole verification (WormholeTransceiver contract).

Specifications

• [x ] Manual NTT transfer: User incurs gas costs on both the source and destination chains, requiring 2 transactions.
• [x ] Automatic NTT transfer: User incurs gas costs and relayer fee on the source chain only, requiring 1 transaction. The relayer completes the transfer on the destination chain. Standard relayers are used for transfers between EVM chains, while specialized relayers are used for transfers to and from Solana.

Error Cases

• Source chain rate-limits (outbound): If the user would be rate-limited on the source chain, display a warning message and prevent the initiation of the transfer.
• Destination chain rate-imits (inbound): If the user is rate-limited on the destination chain, display a warning message and mention clearly that the user will need to resume the transfer in a new transaction after the rate limit expires. Also display when the rate limit expires. Display a warning if the user would likely be inbound rate-limited before the transfer on the source chain is even initiated.
• [x ] Source chain contract paused: If the contract is paused on the source chain, prevent the user from initiating a transfer.
• Destination chain contract paused: If the contract is paused on the destination chain, prevent the user from initiating a transfer.
• Standard relayer delivery failure: Display an error message with the revert reason. NOTE: Re-delivery support is out of scope.
• Specialized relayer delivery failure: Delivery should be guaranteed unless the contract reverts (gas limit too low or misconfigured).
