Each bridge completes the full triangle before the next starts, so inventory returns to origin and only fees burn.","Slippage vs quote: realized fee minus quoted fee, in USD (bridge_quote_slippage_usd). Realized fee is the ticket minus what actually landed on the destination, read from the balance delta; quoted fee is the ticket minus the output the quote promised, one definition for every bridge. Near zero means the settlement matched the quote; positive means it settled worse; negative means it beat the quote.","Why not the providers' own fee fields: some mix in gas paid in the native token, which the realized fee (ticket minus landed) can never contain, so one bridge read a constant negative offset at every ticket size. Both sides of the subtraction are now defined against the ticket.","All-in gas: our own on-chain gas to execute (approve plus deposit), measured as the source-chain native balance delta before and after (bridge_exec_gas_usd). This is the cost the user bears on top of the bridge fee.","Realized fee: ticket minus the value that landed on the destination chain, in basis points of the ticket (bridge_exec_realized_fee_bps), so $3 and $30 executions compare. Published only for settled executions whose destination balance was read on-chain; a leg whose credit was not visible within 30 s publishes nothing and is counted in bridge_realized_fallback_total.","Ticket sizes: $3 daily and $30 on Monday and Thursday, pooled. Small on purpose, since this measures the quote-to-settlement gap, not large-ticket depth. Window: 7 days, about 7 to 9 executions per bridge and corridor.","Region: EU-West only. The execution node runs a single wallet, so a second origin would race the same inventory.","Cohort: Mobula, Relay, LI.FI and Near Intents, the bridges executed on all three legs. Quote-only providers are covered by the bridge-fee and bridge-quote-latency benchmarks."],"license":"CC-BY-4.0"}
