Corn Review 2026: A Bitcoin-Gas Layer 2 for BTCFi

Corn is an Ethereum Layer 2 network built on the Arbitrum Orbit stack. Its stated aim is to give Bitcoin a role in DeFi by letting a tokenized form of BTC pay for gas on an Ethereum-compatible chain.

The network uses two tokens. BTCN, or BitCorn, is a hybrid tokenized Bitcoin pegged 1:1 to BTC and serves as the gas token. CORN is the network's own token, which reportedly launched through a token generation event on March 28, 2025.

Reported funding includes a $6.7 million seed round in August 2024 and a further $1.5 million in November 2024. Named infrastructure partners include Arbitrum, LayerZero, Dune and Conduit, and apps such as Curve, Camelot and Oku are reported on the network. The project's homepage could not be reviewed, so details such as the team, audits and fee levels are not confirmed here.

Corn is a Layer 2 network that settles to Ethereum and uses the Arbitrum Orbit framework. Users run smart contracts and DeFi apps on it much as they would on other Ethereum-compatible chains, but fees are paid in BTCN rather than ETH.

BTCN is described as a tokenized Bitcoin pegged 1:1 to BTC. Sources differ on whether it is backed directly by native BTC or by wrapped Bitcoin such as cbBTC and wBTC held by custodians, which is why reading the official documentation matters. Users bring Bitcoin-linked assets in through bridges and routing partners, convert them to BTCN, and then use them for gas or in DeFi.

The separate CORN token sits alongside BTCN. One source describes an incentive model called popCORN meant to align ecosystem participants, and another says the network uses proof-of-stake. Details of how these work are best checked against the project's own materials.

Corn does not publish a fee schedule in the sources reviewed. Transaction fees are paid in BTCN, the network's gas token, so the cost of each action depends on network conditions and the BTCN price.

Bridge fees, swap fees and app-level charges are set by the third parties involved, such as bridge providers and DEXs. Users would see them in the wallet or app confirmation screen before signing.

Corn's security rests on several layers: the Arbitrum Orbit chain, the bridges that move assets in, the custodians behind BTCN, and each DeFi app used. Custody by Coinbase and BitGo is mentioned in one source, which brings counterparty and regulatory exposure on top of smart-contract risk. No audit reports, bug bounty details or incident history appear in the sources reviewed, and the project does not state a licence.

Tokenized Bitcoin pegs can break if backing is compromised or redemptions fail, and bridges are a frequent target for exploits in crypto generally. Because sources disagree on whether BTCN is backed by native BTC or wrapped tokens, verify the mechanism in the official documentation before depositing.

Corn is for Bitcoin holders curious about BTCFi who want Ethereum-compatible DeFi while keeping Bitcoin exposure, and for developers who want to deploy on an Arbitrum Orbit chain with a BTC-based gas token. It is less suited to users who avoid bridges, custodians or token volatility.
