Addresses & ABIs

This page is the source of truth for contract addresses and the minimal ABIs your dashboards/SDKs need. Addresses are grouped by network; ABIs are stable across networks. Full admin surfaces live in the Contracts section.

⚠️ Always verify checksummed addresses on the official explorer and announcements. Core contracts are UUPS‑upgradeable—use the proxy address (listed here), not the implementation.

Networks

Network	Chain ID	Explorer
Local (Anvil/Hardhat)	31337	—
Polygon Amoy (Testnet)	80002	https://amoy.polygonscan.com
Polygon Mainnet	137	https://polygonscan.com

We’ll update addresses below as deployments happen (Testnet → Mainnet). If a value is —, it has not been published yet.

SylanVesting owner: same OWNER Safe.

Tip: When verifying a proxy, look for the EIP‑1967 implementation slot on the explorer to view the current logic address. Your dapp should call the proxy address.

Minimal ABIs (for dapps/SDKs)

These ABIs cover the common read/write calls used by the marketplace UI. Admin/governance methods are documented on each contract’s page under Contracts.

Verification checklist (before publishing)

Addresses are checksummed and match explorer pages.
Proxies verified; implementation address visible via EIP‑1967 slot.
ABI JSONs match deployed bytecode (no stale build).
Networks table updated (Testnet → Mainnet).
Changelog entry created in Deploy → Verifications.
