May 19, 2026 Wave SOL.3 · 02c7ecb

Solana payment rail live · cross-chain settlement.

  • featSolana buyer-side spl-transfer scheme live — exact buyer-broadcasts + partial-sign with 3 facilitators per chain (failover <500ms).02c7ecb
  • featCross-chain settlement V1 — Mayan bridges (buyer chain → seller chain). Same-chain settlement strict; no cross-chain swap on quote.—
  • featPitch site honest — « 3 facilitators per chain · cross-chain settlement bridges ». Vercel + VPS deployed.—
  • feat1517 tests / 0 fail.—
May 18, 2026 Wave G3 · in progress

Multi-chain site + /proof refonte. (in progress)

  • fixHero pill rolled back — earlier "12 wallets, 6 chains, 9 facilitators, 0 custody" wording was numerically misleading (counts mixed Tier 1 + Tier 2 with runtime reality). Replaced with "Pay on Base or Polygon today · Solana coming next · 0 custody" until Wave SOL ships.—
  • feat/proof page refonte — live table fetching /v1/_status with runtime-driven counts (no hardcoded marketing numbers).—
  • featSDKs Node / MCP / n8n — chain param added (default "base", fully backward-compatible), local edits only.—
  • feat4 OG cards refresh — Designer Opus, aligned multi-chain branding.—
  • docsMulti-chain doc audit — Tier 2 chains (Arbitrum, Optimism, Avalanche) documented with curl snippets.—
May 18, 2026 Wave G2 · 20260518-155822

  • feat3 new chains live as settlement infrastructure (reported by /v1/_health): Arbitrum One (eip155:42161), Optimism (eip155:10), Avalanche C-Chain (eip155:43114). Buyer-side 402 quotes still accept Base + Polygon only.a976104
  • feat/v1/_health reports settlement infrastructure across ["base","solana","polygon","arbitrum","optimism","avalanche"]. Buyer payment endpoints today accept Base and Polygon; Solana ships in the current Wave SOL.—
  • featUSDC Circle native on each Tier 2 chain — verified on-chain (decimals=6, symbol="USDC").b7095fe
  • featSettlement via CDP managed TEE on each chain — no raw private key on VPS.—
  • feat1469 tests / 0 fail (+155 vs G1.x baseline 1314).—
May 17–18, 2026 Wave G1 + G1.x · 20260518-143018

Multi-chain core — Base + Polygon buyer-side live; Solana settlement only.

  • featBuyer payment live on Base and Polygon via accepted_chains[] exposed on first-party endpoints in /v1/_meta. Solana shipped as settlement infrastructure only; buyer-side 402 quotes rejected Solana at runtime — corrected in current Wave SOL.101fdc8
  • featMulti-facilitator stacks per chain (external broadcasters + local-key signer). No single point of failure per chain. Live count on /proof.—
  • featPrimary recipients self-custody — Base + Polygon share EVM addr 0xD6E8…2878, Solana Gt9E…U8w8. 0 custody.—
