Avalanche vs Optimism

Avalanche leads on 5 of 6 shared benchmarks, Optimism on 1. Avalanche wins on Fastest free public RPC for Ethereum, BNB, Polygon and 23 more chains (82 ms vs 169 ms), Fastest Wormhole VAA finalization by source chain, live latency (4.27 s vs 17.5 min), Fastest Chainlink CCIP source chain by end-to-end delivery latency (13.89 s vs 12.5 min), Fastest LayerZero source chain by end-to-end message delivery (26.90 s vs 1.6 min). Optimism wins on Cheapest blockchain transaction fee, live across L1 and L2 chains ($0.0000025 vs $0.00144). Data as of 2026-10-11 UTC.

Latency is conditional on success: the harness times only calls returning a valid fresh block, so a mostly-failing endpoint can post a fast p50. Rows below 50 percent success are degraded; unresponsive probes pin below the table. The All chains aggregate favours single-chain foundation endpoints (Base, Binance, Arbitrum, Optimism, Avalanche officials) since they rank on one chain only; use a chain tab for honest comparison. Dead endpoints (cloudflare-eth POST returns -32603) are excluded.

Stablecoin float is where dollars are parked, not what they do. A chain can take in a billion that sits idle, and lose float to a single issuer redeeming. The figure is DefiLlama's chain-wide pegged-USD aggregate, every issuer combined; it does not separate a bridge inflow from a native mint, and a dollar bridged to an L2 counts on both chains, so rows are not additive. Read the net dollars with the percentage beside them: the same $400M is a rounding error on Ethereum and a doubling elsewhere.

How this pair was selected

Auto-generated pairs require: both providers in the same benchmark for seven consecutive days, at least 1000 samples per provider, observable third-party search demand, and a public /products/[slug] page on OCB. Editorially curated pairs (like this one) may publish early when search demand is high and data is accruing; panels with fewer than 100 samples are shown as provisional. The full pair ledger is versioned in the public repo.

Live data refreshes via ISR within 60 seconds of a new run. Sources are the same Prometheus queries surfaced on the parent benchmark pages.
