Custody & key management
Bitlendex never holds your BTC or your keys. The NEAR Intents bridge holds the BTC you deposit, and immutable smart contracts hold the record of your collateral.
Who holds your BTC
The NEAR Intents bridge holds the BTC you deposit. Bitlendex never holds it. After your deposit confirms, the bridge moves the BTC from your deposit address to its shared Bitcoin treasury.
Collateral you can check
On a Bitcoin block explorer such as mempool.space, you can see your deposit arrive at your deposit address and then move to the bridge's treasury. On NearBlocks, the NEAR block explorer, the Borrow Executed transaction on your Activity page shows the 1:1 BTC token moving into the lending contract as your collateral.
Immutable smart contracts
No admin keys, no upgrade paths. Loan terms are enforced by code that cannot be altered after deployment, by Bitlendex or anyone else.
Native BTC, no WBTC
Your BTC stays on the Bitcoin network and is never wrapped into WBTC or moved to Ethereum. When your deposit confirms, a 1:1 BTC token on the NEAR network is credited to your account. When you confirm your loan, that token is locked in the lending contract as the record of your collateral. When you repay, the lock is released and the bridge sends your BTC to a Bitcoin address you choose.
Audits & verification
The lending contracts have been through five independent security reviews across four firms. Full reports are hosted here — readable by anyone, including search engines and AI agents.
