🟢 The simple version
Plain English — no jargon. Start here.
Corn is an Ethereum Layer 2 blockchain where Bitcoin — specifically a wrapped BTC token called BTCN — is the native gas token used to pay transaction fees, making it the first L2 designed specifically to give Bitcoin a productive DeFi use case on Ethereum.
Why use Bitcoin as gas?
Most Ethereum L2s use ETH as gas. Corn uses BTCN (a wrapped BTC derivative). The idea is to capture the massive pool of BTC that sits largely idle — Bitcoin holders typically hold without using BTC for anything productive, because Bitcoin's own chain has minimal DeFi. By making BTC the gas token of a full EVM L2, Corn gives BTC holders a way to use their Bitcoin in DeFi applications — lending, swapping, yield strategies — while their BTC pays for the transactions themselves.
This creates a pull towards BTC deposits: if you want to use Corn's DeFi ecosystem, you need BTCN for gas. BTC holders are the natural users of the chain, which positions Corn as a "Bitcoin DeFi chain" built on Ethereum security.
BTCN — the gas token explained
BTCN is a wrapped BTC representation specific to Corn. To use Corn, users bridge BTC (via cbBTC, WBTC, or other wrapped BTC forms) and receive BTCN at a 1:1 ratio. BTCN is used to pay gas fees — similar to how MATIC pays gas on Polygon or ETH pays gas on Arbitrum. The BTC underlying BTCN is not locked idle; it can be deployed into Corn's DeFi protocols to earn yield while simultaneously being used as gas.
Is CORN legal in India?
Yes. CORN qualifies as a Virtual Digital Asset (VDA) under Indian law. 30% tax on gains and 1% TDS applies. Always consult a tax professional.

Corn's technical architecture
Corn is built as an Ethereum L2 using the OP Stack (the same framework as Optimism and Base), giving it EVM compatibility and Ethereum-inherited security. The novelty is purely in the tokenomics: the native gas token is BTCN instead of ETH. Ethereum L2 infrastructure (sequencer, bridge contracts, dispute resolution) remains standard.
The CORN governance token is separate from BTCN. CORN is used for governance and protocol incentives — distributing rewards to BTC depositors, liquidity providers, and ecosystem builders. The dual-token structure separates the utility layer (BTCN for gas) from the governance layer (CORN for ownership and incentives).
Any BTC on Corn is a wrapped representation — BTCN backed by cbBTC, WBTC, or similar. Wrapped BTC products carry custodial or smart contract risk: if the underlying wrapper (BitGo for WBTC, Coinbase for cbBTC) has issues, BTCN's backing is affected. This is an additional risk layer vs using native ETH on standard L2s. Live data: CoinGecko
Corn vs other Bitcoin L2s
Multiple projects are building "Bitcoin L2s" — but most are building directly on Bitcoin's settlement layer (Stacks, Merlin, BOB). Corn takes a different approach: build on Ethereum L2 infrastructure (more mature, more DeFi-ready) but make BTC the economic primitive. This means Corn gets full EVM compatibility and Ethereum security, at the cost of not being a true Bitcoin-layer chain. For BTC holders who want DeFi yields without converting to ETH, Corn offers a unique positioning.

For the technically curious.
Key facts
- Token: CORN (governance + incentives)
- Gas token: BTCN (wrapped BTC — not CORN or ETH)
- Chain type: Ethereum L2 (OP Stack)
- EVM compatible: Yes — full Solidity/Vyper support
- BTCN backing: cbBTC, WBTC, other wrapped BTC (1:1)
- Target user: BTC holders wanting EVM DeFi without selling BTC
- vs Stacks: Corn is Ethereum L2 (full EVM); Stacks is Bitcoin-native (Clarity language)
- vs Base: Same OP Stack tech; Corn uses BTC gas vs ETH gas
- Risk: Wrapped BTC custodial/bridge risk stacked on L2 risk
The BTC productive yield thesis
Corn's core thesis is that BTC is the largest underutilised asset in crypto: $1T+ in market cap with almost none of it earning yield on-chain (Bitcoin's native chain has no smart contracts; bridged BTC on Ethereum is a small fraction of supply). If even 2–5% of BTC supply moves into Corn to earn DeFi yields — lending, AMM fees, restaking — the resulting TVL would make Corn a top-5 DeFi chain instantly. The bet is that BTC holders' appetite for yield, combined with a BTC-native gas experience, can capture a meaningful share of dormant BTC capital.
