Status: Partially implemented. AGG payment routing and Hyperlink smart payment links are live. The full on-chain Monetization Contract (automated split execution, buyback executor, Treasury PDA) is planned.

​
Purpose

Trustlessly ingest campaign budgets and platform fees, then algorithmically distribute proceeds. The Monetization Contract is part of the 555x402 protocol suite, which includes:
  • AGG (Payment Aggregator): Facilitator router (Rust, Kafka) with multi-facilitator scoring, HTTP 402 middleware, and sub-2-second Solana settlement. Live on-chain at program 2XfsNMcrJCbkaEwYfg6zpNXKipmSDY3tvMUK1KVs7bfV.
  • Hyperlink (Smart Payment Links): Gasless, multi-chain USDC payment links at 555hyper.link. Supports Solana, Base, and Polygon via Circle CCTP V2. Vanity URLs (/@alice), QR codes, webhook system, and claimable payouts.
  • SCEP (State Channel Escrow Protocol): On-chain Anchor program for off-chain accumulation with on-chain settlement.

​
Accounts & Entities

  • Inflow Vault: receives SOL/USDC and other supported tokens via AGG payment router
  • ARP PDA: Audience Reward Pool escrow and reward schedules
  • Buyback Executor: programmatic DEX execution with guardrails (automated pipeline being built; manual burns operational)
  • Treasury PDA: holds funds prior to creator/stakeholder distribution
  • Receipt & Events: program logs for attribution and analytics
  • Hyperlink claimables: pending USDC payouts claimable via payment link

​
Flow

1

Ingest

Campaigns and fees are deposited into the Inflow Vault with metadata for attribution and targeting.
2

Split (ARP / Buybacks / Treasury)

The contract applies the canonical split and updates balances for the ARP PDA, Buyback Executor, and Treasury.
3

Execute Buybacks

≥20% is routed to automated buybacks for the creator economy. Creators can configure a higher percentage within governance bounds.
4

Distribute Treasury

Funds are shared between Creator and Stakeholders per the active split. Stake-weighted votes can adjust the split within a bounded range (e.g., 20/80 to 80/20). Reserves (5% token, 5% SOL/USDC) are set aside.

​
Events & Telemetry

  • InflowReceived(amount, campaignId, asset)
  • SplitApplied(arp, buybacks, treasury)
  • BuybackExecuted(token, amountIn, amountOut, venue)
  • ProfitDistributed(creator, stakeholders, ratios)

​
Safety & Controls

  • Circuit breakers and rate limits for volatile conditions
  • Allow-lists for DEX venues and oracles
  • Time-boxed windows for large batch operations
