Fastest Chainlink CCIP source chain by end-to-end delivery latency
Wall-clock seconds from a source-chain transaction to destination-chain execution for a Chainlink CCIP message, measured across CCIP source chains via the public CCIP Tools API.
TL;DR. As of , Solana leads ccip delivery at 1.3 min (p50, 24h) on Fastest Chainlink CCIP source chain by end-to-end delivery latency. Source: OpenChainBench, https://openchainbench.com/benchmarks/chainlink-ccip-latency.
Chainlink CCIP (Cross-Chain Interoperability Protocol) is a cross-chain messaging network operated by the Chainlink DON (Decentralized Oracle Network). A CCIP message flows through three stages: source transaction submitted, DON commits a merkle root once source-chain finality is reached, then a destination executor performs the delivery. This benchmark measures end-to-end delivery latency by source chain: wall-clock seconds from source-tx timestamp to destination-tx timestamp, computed for every CCIP message the public CCIP Tools API returns as `status: SUCCESS`. Every value on this page is an observation of real user traffic (Aave, Vault protocols, cross-chain token bridges), never a canary transaction. Latency distribution is dominated by source-chain finality: Ethereum-source lanes routinely take 12-15 minutes waiting for Casper FFG finalization before the DON commits; L2s that inherit Ethereum finality show similar structural floors; sub-second BFT chains (BNB, Solana) finalize fast and land end-to-end in low-single-digit minutes. Choosing a source chain for a CCIP integration is a choice about that structural finality tax.
Methodology
For each of the CCIP-supported source chains with non-trivial mainnet traffic, we measure the wall-clock latency between a source-chain transaction submission and destination-chain execution. Data source: the public `https://api.ccip.chain.link/v2/messages` endpoint, polled every 60 seconds. Each `SUCCESS` message's `receiptTimestamp - sendTimestamp` is one observation of end-to-end latency, recorded in a per-source-chain histogram. The p50/p90/p99 shown here are computed via Prometheus `histogram_quantile` over the last 24 hours.
Frequently asked
What is Chainlink CCIP?
CCIP (Cross-Chain Interoperability Protocol) is a cross-chain messaging network operated by the Chainlink DON. It underpins production integrations at Aave, Vault protocols, and multiple cross-chain token bridges. The security model relies on a Risk Management Network (RMN) and finality-aware settlement , the DON waits for source-chain finality before committing a merkle root.
What does this benchmark measure?
Wall-clock seconds from a source-chain transaction to destination-chain execution for CCIP messages that reached `status: SUCCESS`. It is a passive measurement of real user traffic , every observation is a CCIP message that a real user or protocol actually sent.
Why is Ethereum-source so much slower than other chains?
CCIP intentionally waits for source-chain finality before its DON commits a merkle root. On Ethereum, that means waiting for Casper FFG finalization , typically 12-15 minutes, up to ~25 minutes in adverse epochs. This is a security choice, not a performance bug. Sub-second BFT chains (BNB, Solana) finalize quickly, so their end-to-end latency is dominated by DON work + destination execution rather than finality wait.
How does the data get sourced?
The harness polls the public `https://api.ccip.chain.link/v2/messages` endpoint every 60 seconds and records `receiptTimestamp - sendTimestamp` for each new `SUCCESS` message. The endpoint is Chainlink's own CCIP Tools API , no auth required, ~200ms round-trip. No canary transactions are sent, no user funds are used.
Which source chain is fastest for CCIP today?
Solana currently leads at 1.3 min (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.
Can I compare this to the Wormhole VAA bench?
Only carefully. CCIP measures end-to-end delivery (source tx → destination execution) after waiting for source-chain finality, while the Wormhole VAA bench measures observation → quorum (pre-finality signing). On Ethereum-source lanes CCIP will look 12-15 minutes slower, but that reflects a security choice, not raw protocol speed. The cross-chain messaging comparison meta-bench exposes a finality-normalized column so the pure DON+execution work is directly comparable to Wormhole's signing latency.
