Competing platforms

Several projects are helping users move liquidity across chains. Some are simple “bridges” while others, like Axelar, Thorchain, and Zetachain have their own native blockchain that allows for cross-chain smart contracts. Most focus on transferring value through token wrapping (with the exceptions being Stargate, Chainflip, and Thorchain). Most use Threshold Signatures (TSS) instead of multisignatures, with Wormhole being the main outlier. Stargate is built on LayerZero, and LayerZero’s message passing will be built on Chainlink oracles. It appears that currently, Stargate is using FTX, Polygon, and Sequoia as oracles; however, if Stargate moves to Chainlink as an oracle provider, Stargate will rely on Chainlink security. Chainlink has, to some extent, adopted Threshold Signatures (“We plan to adopt some form of aggregate or threshold signature scheme instead of the multisignatures used so far.”), and SGX (with its acquisition of Town Crier), so in principle, Stargate could use these features, but they are not widely used (and not currently mandated) by the Chainlink ecosystem.
