Glossary

The terms behind every table on upswap, with examples from run #538.

Definitions

Basis point (bps)
One hundredth of a percent: 1 bps = 0.01% of the amount sent. On a $200 transfer, 1 bps is $0.02. Example: in run #538 the cheapest $200 quote on the first sampled route cost 0.16 bps, about $0.003.
Net received
The USD value of what arrives on the destination chain minus any extra fee the API reports separately (amount_out_usd − fee_extra_usd). Rankings sort by this.
Cost excl. gas
Input value minus net received, expressed in bps of the input. Source-chain gas is not included because the APIs estimate it inconsistently.
Source-chain gas
The transaction fee on the chain you send from, as estimated by the quote API. Shown in its own column when returned; Across gas is never counted in rankings (decided policy).
Tier
Each route is quoted at three fixed sizes: $20, $200 and $2,000. Fixed fees weigh more at $20; slippage and liquidity show up more at $2,000.
Run / snapshot
One pass of the collector over every route and tier with a single price snapshot. Run #538 produced 2,195 quotes from 1,218 requests. See the status page for the full log.
Rankable quote
A successful live quote that is not above input and not a fee-schedule row. At $200 in the latest run there were 680 rankable quotes across all routes.
Quote above input
A quote whose net received is higher than what you send. These are listed with a warning but excluded from rankings until a real transfer verifies them (1 at $200 in the latest run).
Fee-schedule (reference) row
A cost computed from a published fee schedule rather than a live quote, e.g. Circle CCTP. Shown for reference, never ranked (44 such rows at $200 in the latest run).
Aggregator
A service that routes your transfer through one of several underlying bridges, e.g. LI.FI or Bungee. Their public quote APIs can include a platform fee; 364 of the latest $200 quotes carried one.
Intent-based bridge
A design where the user states the desired outcome and a third-party filler (solver) delivers funds on the destination chain, settling with the protocol afterwards. Settlement and dispute details differ by protocol and are marked 待核实 on each review.
Integrator ID
An identifier some APIs attach to requests. upswap sends Across integrator ID 0x03db with an app fee of 0 and earns nothing from quotes.
ETA (quoted)
The arrival time the API estimates when quoting. It is not a measured arrival; measured times come only from real-money tests.
Real-money test
A transfer we actually send and track end to end. None have been run yet; they are planned after launch and will be published with transaction hashes.
Data gate
The minimum evidence before a page is published. Bridge reviews: rankable quotes on >= 5 distinct routes and in >= 5 runs, 7 days before the latest run; bridges whose 7-day rankable quotes all come from the sources added 2026-10-31 also need >= 14 UTC days of rankable quotes from them. Comparisons: both bridges pass the bridge gate, >= 8 common routes and >= 90 head-to-head $200 observations in 7 days; indexable only if >= 2 common routes have real-money tests.
Head-to-head observation
One run in which two bridges both returned a rankable $200 quote on the same route. Comparison pages count only these, so both sides faced the same prices and moment.
Raw response hash (sha256)
Every API response is archived and fingerprinted, so any number on the site can be traced to the exact response it came from.
