Fastest Axelar GMP source chain by end-to-end delivery
BNB Chain leads axelar gmp delivery at 25.00 s (p50, 24h) on Fastest Axelar GMP source chain by end-to-end delivery. Wall-clock seconds from a source-chain transaction to destination-chain execution for an Axelar GMP (General Message Passing) call, measured across supported source chains via the public AxelarScan API.
TL;DR. As of , BNB Chain leads axelar gmp delivery at 25.00 s (p50, 24h) on Fastest Axelar GMP source chain by end-to-end delivery. Source: OpenChainBench, https://openchainbench.com/benchmarks/axelar-gmp-latency.
Axelar is a cross-chain communication network built on a Cosmos-SDK chain plus a validator-attested gateway on every supported destination. A GMP call flows through four stages: source-chain tx (call), Axelar validator quorum confirms it (confirm), destination Gateway ApproveContractCall (approved), destination executor runs the receiver (executed). AxelarScan's API pre-computes the latency between each stage in seconds; this benchmark surfaces two of them: `call_confirm` (source to quorum) and `total` (source to destination executed). Every value on this page is an observation of real user traffic, Squid Router, ITS, Interchain Amplifier apps. Latency distribution reflects Axelar's own Cosmos block time (6 seconds, so sub-6s latencies quantise to 0 or 6s), destination-chain block time for the approve+execute stages, and validator round-trip.
Methodology
For each Axelar-supported source chain with mainnet traffic, we measure two latencies from AxelarScan's `time_spent` object: `call_confirm` (source tx to validator quorum) and `total` (source tx to destination execution). Data source: the public `https://api.axelarscan.io/gmp/searchGMP` endpoint, polled every 60 seconds for the 25 most recent EXECUTED messages. Both values are already computed in seconds server-side; the harness just converts to milliseconds and records per-source-chain histograms. The p50/p90/p99 shown here are computed via Prometheus `histogram_quantile` over the last 24 hours. See cross-chain-messaging-latency for the side-by-side comparison across all four end-to-end protocols on the same shared observation stack.
Frequently asked
What is Axelar GMP?
Axelar General Message Passing is Axelar's cross-chain message API. Applications call the Axelar Gateway on the source chain, Axelar validators observe the event and reach quorum on a Cosmos block, and a destination-chain Gateway then approves and executes the message. It is the primitive underneath Squid Router, ITS, and the Interchain Amplifier ecosystem.
What does this benchmark measure?
Two things. `axelar_gmp_confirm_latency_ms` is the time from source tx submission to Axelar validator quorum confirmation, directly comparable to Wormhole VAA finalization. `axelar_gmp_e2e_latency_milliseconds` is source tx to destination execution, comparable to LayerZero, Chainlink CCIP, and Hyperlane end-to-end delivery.
Why is there a visible 6-second floor on some chains?
Axelar itself runs on a Cosmos chain with 6-second Tendermint blocks. Sub-6s latencies always quantise to 0 or 6 in the reported `time_spent`. This is a property of Axelar's own consensus, not our measurement , the same floor would appear in any latency reading based on Axelar block timestamps.
How does the data get sourced?
The harness POSTs `{size: 25, status: executed}` to `https://api.axelarscan.io/gmp/searchGMP` every 60 seconds and records both `time_spent.call_confirm` and `time_spent.total` for each new message. The endpoint is Axelar's own scan API , no auth required. No canary transactions are sent.
Which source chain is fastest for Axelar today?
BNB Chain currently leads at 25.00 s (p50 over the last 24 hours). The leaderboard re-sorts continuously against fresh Prometheus samples; the ranking on this page is the ranking right now.
Why is Solana missing?
Axelar mainnet does not support Solana yet. A Solana devnet Amplifier is in testing as of early 2025, but there is no mainnet GMP traffic to observe. The bench will add Solana as a source chain when Axelar ships mainnet support.
