DeSpell Onchain Observatory

How bridges and swaps that other people already executed actually performed, measured from public chain logs on Base, Arbitrum and Ethereum. Totals only: no addresses, no transaction hashes, no individual transfers.

DeSpell uses these numbers to filter card candidates. They do not change how live quotes are ranked.

Bridge corridors

Confirmed: share of departures whose arrival event we saw within 2 hours. Arrival times cover confirmed transfers. Fee: amount sent minus amount received, in basis points.

Method and limits

  • We read public bridge and swap events with our own RPC reads. No vendor API and no user data are involved.
  • CCTP transfers and Stargate bus rides carry no shared id, so they are matched by amount and recipient. Their confirmed rates are lower bounds.
  • Fees leave out source chain gas, LayerZero messaging fees and deBridge fixed fees, which are paid separately in the native token.
  • Values are rounded to two significant digits before they are combined, and quantiles are nearest rank.
  • Cells with fewer than 50 samples show counts only.

DeSpell 온체인 관측소

다른 사람들이 이미 실행한 브릿지와 스왑이 실제로 어떻게 끝났는지를 Base, Arbitrum, Ethereum의 공개 체인 로그로 잽니다. 합계 숫자만 싣고 주소, 거래 해시, 개별 전송은 싣지 않습니다.

DeSpell은 이 숫자로 카드 후보를 거릅니다. 실시간 견적의 순위는 바꾸지 않습니다.

브릿지 코리도

확인률은 출발 뒤 2시간 안에 도착 이벤트를 본 출발의 비율입니다. 도착 시간은 확인된 전송만 셉니다. 수수료는 보낸 양에서 받은 양을 뺀 값(bps)입니다.

방법과 한계

  • 공개 브릿지·스왑 이벤트를 우리 RPC 읽기로 모읍니다. 벤더 API와 사용자 데이터는 쓰지 않습니다.
  • CCTP 전송과 Stargate 버스는 공통 식별자가 없어 금액과 받는 주소로 짝짓습니다. 그래서 이 둘의 확인률은 하한입니다.
  • 수수료에는 출발 체인 가스, LayerZero 메시징 수수료, deBridge 고정 수수료가 빠져 있습니다. 모두 네이티브 토큰으로 따로 냅니다.
  • 값은 합치기 전에 유효숫자 둘로 반올림하고, 분위수는 최근접 순위로 잽니다.
  • 표본이 50건 미만인 칸은 건수만 보입니다.
