Axelar supports smart contracts, making it unique among cross-chain networks – delivering true chain abstraction for both users and developers with minimal overhead.
Today, Axelar connects more blockchains than any other interoperability provider – and the gap is widening. Axelar is truly the shortest path to scale.
Axelar runs battle-tested proof-of-stake verification. Risk is further mitigated via superior topology and application-layer policies like rate limits.

Axelar supports smart contracts at the cross-chain layer, giving blockchain developers super powers to scale their applications with ease.
Send a token cross-chain to Uniswap with instructions to execute a trade.
Send a 'safeMintO function call to mint a real-world asset as an NFT on a connected chain.
Users from various blockchains pick a number and place a bet in the token of their choice.
