The short answerAxelar routes cross-chain messages through its own proof-of-stake chain, so the entities verifying your transfer are bonded and slashable rather than merely trusted. That is a real improvement over unbonded multisigs, paid for in latency, fees and a validator set smaller than a major L1's.

What we liked, and what fell short
Liked- Validators are bonded and slashable rather than merely trusted
- Broad chain coverage with general message passing
- No successful exploit to date
Fell short- Adds a full consensus round-trip, so transfers are slow
- Validator set is smaller than a major L1's
Why the marks landed where they did
The weakness in most bridge designs is that the verifying parties have nothing at stake. Axelar's answer is to make verification a proof-of-stake consensus problem: validators bond tokens, sign for cross-chain messages, and can be slashed for misbehaviour.
Why bonding changes the calculus
An unbonded multisig signer who colludes loses nothing but reputation. A bonded validator loses capital. That converts bridge security from a trust question into an economic one, where the cost of attacking exceeds the gain as long as the bonded value is large enough relative to the value being secured — which is the same logic that secures proof-of-stake chains generally.
The size question
Axelar's validator set and total bonded value are much smaller than Ethereum's or Cosmos Hub's. For a transfer of moderate size that is ample; for very large transfers, the economic security should be compared against the amount being moved. This is the right analysis to perform and almost nobody performs it.
Cost and speed
A full consensus round-trip means transfers take longer than intent-based bridges and cost more than CCTP. General message passing is supported, so Axelar carries contract calls as well as tokens.
Who should use it
Users and applications wanting an economically secured cross-chain route with broad coverage, sized against the network's bonded value. For speed on EVM routes, Across is faster; for USDC specifically, CCTP is safer.
FAQ
How is Axelar different from a multisig bridge?+
Its validators bond tokens and can be slashed for misbehaviour, so attacking the bridge has a direct economic cost rather than only a reputational one.
Is Axelar's validator set large enough?+
It is smaller than a major L1's, so for very large transfers the bonded value should be compared against the amount being moved.
Why are Axelar transfers slower?+
Each transfer requires a full consensus round-trip on the Axelar chain before execution on the destination.
Has Axelar been exploited?+
No successful exploit is on record.
