feat(facilitators): add 15 Coinbase CDP relayers on Base (active 2026-06-13)

[Sigmabrogz]

Summary

Adds 15 Coinbase CDP facilitator relayer addresses on Base that began settling x402 payments on 2026-06-13 but are not yet in coinbase.ts. Because x402scan attributes settlements by the relayer (msg.sender) that submits the on-chain transferWithAuthorization, settlements from these unlisted relayers are currently not counted toward Coinbase — undercounting Coinbase facilitator volume on Base.

Why these are Coinbase CDP relayers (on-chain evidence)

All 15 addresses share the on-chain fingerprint of the relayers already listed in coinbase.ts:

1. Same gas funder. Every one of the 15 is funded for gas by 0x022e88961EfFbFD1E5ECDe0fbd89e7006d9B05ef — the same wallet that funds relayers already attributed to Coinbase here (e.g. 0x8f5cb67b…, 0x67b9ce70…, 0xa32ccda9…). Shared funding wallet ⇒ same operator.
2. Same behaviour. Each only calls transferWithAuthorization on native USDC (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913), settling EIP-3009 x402 payments.
3. Multi-merchant. They settle for many distinct recipient merchants, not a single seller — i.e. shared facilitator infrastructure.
4. New batch. First transaction 2026-06-13 for all 15 — a relayer rotation/expansion that post-dates the last sync (the existing newest entries are dated 2025-12-16).

They are interleaved block-by-block with the already-listed Coinbase relayers settling identical payments.

How to verify

For any address above, on Base:

• It is funded by 0x022e8896… (same as existing Coinbase relayers), and
• Its outbound txs are all transferWithAuthorization to the USDC contract for varied recipients.

Happy to adjust formatting or split per-token if preferred.
