## ICO Sylan Description:

**Sylan is a decentralized API marketplace on Polygon that connects API/data providers, node operators, and consumers.**

Providers list their APIs with transparent pay-per-call or subscription plans. Consumers pay in SYL, which is locked in an on-chain escrow contract for each request or subscription.

A network of independent nodes fetches responses from the provider APIs, reaches quorum on signed snapshots (EIP-712), and only then settles the escrowed funds based on success or failure. This creates a trust-minimized flow: lock → request → vote → settle.

**Key features:**

- Escrowed SYL payments for each request or subscription, with automatic settlement and transparent balances.
- Quorum-based consensus on API responses via EIP-712 snapshots and node voting, with rewards/slashing for node performance.
- Configurable API plans (Pay-Per-Call and Subscription) with on-chain pricing, access control, and per-API fee splits between providers, nodes, and the platform.
- On-chain audit trail (EventLogger) emitting structured events for requests, votes, and settlements, enabling explorers, analytics, and dispute resolution.
- Upgradeable core on Polygon (UUPS pattern) with a “Polygon-first” strategy for low fees and fast finality, plus future multi-chain readiness.
- Use cases include crypto market data APIs, Web3 price feeds, AI inference APIs, fintech/FX data providers, and any service where reliable, monetized API access is needed. Sylan turns APIs into on-chain assets with programmable payments and transparent economics.
