Axelar (axelar)

​

Notes

• Uses chain name strings for destination (e.g. “ethereum”, “arbitrum”, “Polygon”) — NOT chain IDs
• sendToken: Simple token transfer. callContract: GMP message. callContractWithToken: Both
• GMP calls require pre-paying gas via GasService or including gasValue in ITS calls
• ITS (Interchain Token Service) enables native cross-chain tokens without wrapping
• Same ITS address (0xB5FB...) across all chains
• tokenAddresses(symbol) to look up the local address of an Axelar-supported token
• Finality: typically 2-5 minutes depending on source chain

function main() {
  // Ethereum's gasService, `0x2d5d7d31F671F86C782533cc367F14109a082712`.
  require(Axelar.GasService != 0);
}
