How to bridge from Polygon to Base

Example quote from 25 September 2026: sending 27,739 POL (~$3,000) from Polygon returns about 1.1179 ETH on Base via Symbiosis, estimated ~35 sec — no wrapped tokens beyond the standard route, fully non-custodial. Symbiosis works as a liquidity meta-aggregator, comparing routes across multiple DEXes and bridge providers and picking the best one by price, fee, and speed automatically. Here's how the flow works:

Pick the source. Set Polygon as source and Base as destination — the POL sits in a Polygon wallet, and the goal is access to Base assets.
Connect wallets. MetaMask on the Polygon side, MetaMask on the Base side. Symbiosis reads the destination address automatically from the connected wallet — no manual paste required.
Enter the amount. 27,739 POL (~$3,000) in this example. Keep enough POL in the wallet to cover network gas.
Review the quote. Symbiosis displays the exact ETH amount on Base (about 1.1179 ETH in this example), the flat Symbiosis fee in USD, and ETA (~35 sec). The quote is locked in before signing — 2% slippage tolerance protects against sudden price moves.
Sign and confirm. Sign the Polygon transaction in MetaMask. ETH arrives in MetaMask once the route completes — track the transfer on Symbiosis Explorer.

About the Polygon to Base route

Why this route. Base is Coinbase's Ethereum layer 2. Lending there runs through Morpho, which powers Coinbase's crypto-backed USDC loans, and Aave; swaps go through Aerodrome and Uniswap.
What you receive. ETH on Base, which pays gas there, so a Morpho deposit or a swap can follow at once. One signature on Polygon starts it; on 28 September 2026, 9,100 POL was quoted at 0.3923 ETH.
Watch out for. Switch your wallet to Base (chain ID 8453) to see the ETH: the 0x address is the same, but the balance is not on Ethereum mainnet. Keep a little POL for the sending gas.
Speed. Median delivery 17 seconds; 90th percentile 46 seconds, over the 90 days to 25 September 2026.

WHY SYMBIOSIS

Secure by design. Proven at scale

Audited in the open

No KYC, no custody, no intermediaries. Audited by Decurity, Zokyo, SlowMist, and Omniscia — 13 public audit reports across 11 protocol modules (Core, MetaRouter v3, Pool, TON Bridge v1+v2, Relayers Network, Staking, Frontend). All reports open-source on GitHub. 4+ years live on mainnet (since March 2022) with zero major security incidents. Active bug bounty program.

Two-layer staking security

Cross-chain transactions routed via Octopools AMM (scans liquidity across DEXs and chains for minimal slippage), then signed by an MPC group via Threshold Signature Scheme (TSS) — no single party can move user funds. Two security layers: Symbiosis PoS Staking (SIS-collateralised relayer nodes) + Symbiotic restaking (additional slash-able collateral). 2/3 stake quorum for epoch changes.

$8B+ across 54 chains

$8B+ total volume bridged across 5M+ transactions from 800K+ unique wallets. Supports 54 networks — more than any other cross-chain bridge (Across 35+, deBridge 30+, Allbridge 20). EVM + non-EVM in one route — Ethereum, Solana, BNB Chain, TON, Tron, Bitcoin, Arbitrum, Polygon, and 46 more. Per-transaction range: $10 to $140,000 — handles retail swaps and whale trades on the same route.

Still have questions?

How do I bridge from Polygon to Base?

Connect your EVM wallet (MetaMask, Rabby, Trust) holding POL, USDC.e, or WETH on Polygon to the Symbiosis app. Select Polygon to Base, choose ETH on Base as the destination token, enter amount (~$10 min), and sign. Symbiosis routes via Octopools AMM with median ~17-second settlement as of September 2026 — one of the fastest corridors in the Polygon cluster.

How long does Polygon to Base take?

Median end-to-end ~17 seconds; 90% of bridges complete under ~46 seconds as of September 2026. Polygon to Base is one of the fastest corridors on Symbiosis because both are EVM-compatible chains with fast finality. Live ETA shown in swap UI.

What are the fees Polygon to Base?

On 28 September 2026, 9,100 POL returned 0.3923 ETH on Base with a $1.35 fee (full cost in the Symbiosis app plus gas), and the fee stayed at $1.35 for 91,000 POL, which returned 3.921 ETH. The exchange rate is already reflected in the amount you receive. Total cost shown live before signing.

What tokens can I bridge from Polygon to Base?

Symbiosis supports POL, USDC.e (Polygon's bridged USDC), WETH, USDT.POS, and other major Polygon ERC-20s as source. Receive ETH, USDC, or other Base ecosystem tokens on Base as destination. UI shows full token list.

Is the Symbiosis bridge safe?

Yes. Symbiosis runs a permissionless relayer network secured by two staking layers — native Symbiosis PoS Staking (SIS-collateralised relayer nodes) and Symbiotic restaking (additional slash-able collateral). Cross-chain transactions are signed by an MPC group using Threshold Signature Scheme (TSS) — no single party can move user funds. Audited by Decurity, Zokyo, SlowMist, and Omniscia (public reports at github.com/symbiosis-finance/audits). Active bug bounty at Immunefi.

Can I bridge POL or MATIC? What's the difference?

Both. POL is the current ticker following the 2024 MATIC→POL rebrand — the underlying token is the same Polygon native asset. Symbiosis supports POL (alias MATIC) as a source token, plus the major Polygon ERC-20s: USDC.e, USDT.POS, WETH, WBTC, AAVE, LINK, UNI, DAI, and others. The swap UI auto-detects whichever symbol your wallet shows.

Can I also bridge from Base back to Polygon?

Yes — same Symbiosis UI handles both directions. See dedicated Base to Polygon guide for reverse-direction details.

Does Symbiosis bridge differ from official Base bridge?

The official Base standard bridge connects Ethereum ↔ Base only (its former interface at bridge.base.org has been retired, and Base now points users to third-party bridge interfaces); standard withdrawals from Base to Ethereum take 7 days. Symbiosis routes Polygon ↔ Base directly via Octopools AMM in median ~17 seconds as of September 2026 — no Ethereum hop, no 7-day delay.
