Cross-chain transactions

[gabririgo]

Summary

Allow pools to perform cross-chain token bridging transactions.

Motivation

In general, tokens will have different levels of liquidity and different liquidity-providing APRs on different chains, which will open opportunities for pools generating yields. Also, some tokens might be available on a few chains only. Given the possibility of creating arbitrage strategies across chains, it is desirable to be able to transfer tokens from 1 supported chain to another within the same pool.

Specification

A cross-chain bridge adapter should be developed. It should allow interaction with a few selected bridges, or all of them at choice.
