Cheap EVM next to Ethereum — now POL

Wallet for Polygon

Polygon is a cheap EVM network next to Ethereum: the same 0x… addresses, fees in fractions of a cent. Since 2024 the network coin is POL (ex-MATIC). In Mitilena you see gas before you sign, and USDC vs USDC.e by different contracts. A free wallet in 30 seconds, no KYC.

Polygon

since 2020 · EVM, Ethereum sidechain

Why Polygon, who needs it, and how this network’s rules differ from the rest — short and to the point.

What for
Cheap stablecoin transfers and apps on Polygon: games, NFTs, payment services.
Who uses it
Anyone who wants an Ethereum-style address without Ethereum fees, and users of services built on Polygon.
Quirk
The network can rewrite recent blocks, so exchanges wait for many confirmations even though a block is two seconds.
Pitfalls

Four Polygon rules worth knowing before you send

Not abstract “crypto risks,” but the rules of this network. For each — what happens, and how Mitilena shows it before the Send button.

Pitfall 01

MATIC became POL

In September 2024 Polygon renamed the coin one-to-one: MATIC → POL. Exchanges and old guides still mix the names, and a MATIC token on Ethereum still exists as a separate contract.

How we do it
In Mitilena the network coin is POL. If a venue says “MATIC (Polygon)” — that is the same coin; “MATIC (ERC-20)” is the Ethereum token — send there.
Pitfall 02

USDC and USDC.e — different tokens

On Polygon there are two USDCs: native from Circle and the older bridged USDC.e. Same price, different contracts — a venue waiting for one will not see the other.

How we do it
We show both under their own names with the contract address. Before withdrawing to an exchange, check which of the two it expects.
Pitfall 03

Two-second blocks, but many confirms

Polygon finalizes through Ethereum, and until then recent blocks can be rewritten. Exchanges ask for dozens or hundreds of confirmations: the transfer shows up right away, credit takes a few minutes.

How we do it
We show transaction status; how long credit takes depends on the venue’s rules.
Pitfall 04

Gas in POL

Like any EVM network: a USDT transfer is paid in the native coin. Without POL on the address, tokens stay stuck.

How we do it
We estimate gas before you sign and warn if POL is short. A swap inside the wallet works even for a tiny amount.

What there is
USDT (bridged from Ethereum), USDC from Circle and the older USDC.e, plus project tokens on Polygon.
Gas
A token transfer is paid in POL.
Freeze
Tether and Circle can freeze an address on Polygon the same way as on Ethereum. Nobody can freeze POL.
Fakes
Check the contract address. USDC and USDC.e are both legitimate but different; “USDT” with a foreign contract is a fake.

FAQ

What people ask about Polygon

Are MATIC and POL the same?

Yes — Polygon renamed the network coin to POL in September 2024 one-to-one. A separate MATIC token on Ethereum is a different contract. In Mitilena the network is POL.

What is the fee on Polygon?

Fractions of a cent per transfer, including USDT. Gas is paid in POL.

Which USDC on Polygon: USDC or USDC.e?

Whichever your venue accepts. Native USDC from Circle is the main one; USDC.e is the older bridged version being phased out.

How long does a Polygon transfer take?

A block is two seconds, but exchanges wait for many confirmations because the chain can rewrite recent blocks. Credit usually takes a few minutes.
