✨ Polygon Bridge New features
In the multi-chain world of 2025, moving assets between Ethereum and Layer-2 networks must be fast, affordable, and secure. Polygon Bridge answers this need by providing seamless transfers of tokens and NFTs between Ethereum Mainnet and Polygon’s high-performance Layer-2. Whether you’re a retail trader, yield farmer, or institutional treasury manager, Polygon Bridge empowers you with choice—balancing speed, cost, and security to suit any use case.
What Is Polygon Bridge?
Polygon Bridge is the official cross-chain gateway built by the Polygon team. It locks your assets on one chain and instantly (or nearly so) mints pegged equivalents on the other. Two complementary bridge paths are offered:
Proof-of-Stake (PoS) Bridge Optimized for everyday transfers, PoS deposits settle in about 2 minutes, and withdrawals finalize in approximately 7 minutes via periodic validator checkpoints.
Plasma Bridge Designed for high-value or compliance-sensitive transfers, Plasma offers instant deposits on Polygon and a 7-day exit challenge period for on-chain fraud proofs—delivering Ethereum-level security.
Core Benefits
Lightning-Fast Transfers
PoS Bridge: Near-instant deposits, rapid seven-minute withdrawals

Ultra-Low Costs
Polygon Gas Fees: Typically under $0.10 per transaction
