BoringDAO (BORING) Explained: What the Crypto Token Is and How It Works
BoringDAO oBTC Bridge Fee Calculator
BoringDAO charges a fixed 0.2% fee for both minting and redeeming oBTC. This fee is applied to the BTC amount being transferred. Additional costs include Ethereum gas fees for the transaction, which vary based on network congestion.
Note: The actual cost of Ethereum gas is not included in this calculator and depends on current network conditions.
If you’ve ever wondered how a Bitcoin can earn yield on Ethereum‑based DeFi platforms, the answer often points back to a niche but ambitious project called BoringDAO. Launched in late 2020, BoringDAO set out to turn non‑ERC‑20 assets into usable tokens on Ethereum, creating a bridge that lets holders move value across chains without giving up ownership. Below you’ll find a plain‑English breakdown of the protocol, its native token, and why the project looks very different today than it did a few years ago.
What Is BoringDAO?
BoringDAO is a decentralized protocol built on the Ethereum blockchain. Its core mission is to create "Tunnels"-bi‑directional bridges that map assets from other blockchains (most notably Bitcoin) to ERC‑20 tokens that can be used in DeFi applications.
The protocol is governed by a community DAO, and the governance authority is embodied in the BORING token (symbol: BOR). Holders of BOR can vote on upgrades, fee structures, and which new assets get added to the bridge network.
Technical Architecture: Tunnels and the oBTC Example
The first and most prominent tunnel is called oBTC. oBTC works by locking real Bitcoin in a custodial vault, then minting an ERC‑20 token that represents a 1:1 claim on that Bitcoin. The minted token can be moved into any Ethereum smart contract-yield farms, lending platforms, or AMMs-just like any other ERC‑20 asset.
Two key parameters keep the system stable:
- Pledging coefficient (k): set between 75% and 100% in version1, ensuring the vault always holds enough collateral to back the minted tokens.
- Commission rates (m, n): a flat 0.2% fee for both minting (depositing BTC) and redemption (withdrawing BTC), plus the usual network gas costs.
All smart‑contract code is built on top of OpenZeppelin libraries, using the ERC20Burnable and SafeERC20 modules for security and upgradeability.
Tokenomics and Market Snapshot (as of Oct2025)
The BORING token follows the standard ERC‑20 format. Its contract address is 0xbc19712feb3a26080ebf6f2f7849b417fdd792ca
. The token supply figures differ across data providers, reflecting a fragmented market reality:
- Etherscan reports a circulating supply of ~1.57billion BORING, a market cap of ~$3.56M, and 24‑hour volume of ~$81.9K.
- CoinMarketCap lists a price of $0.00009456, ranking the token at #6175 with negligible daily volume.
- Kriptomat shows a Euro price of €0.000127 and a 24‑hour drop of 20.89%.
These discrepancies hint at possible token migrations, data‑feed glitches, or the fact that the original bridge services are no longer actively trading on major exchanges.

How the Bridge Works in Practice
For a user who wants to convert BTC into an ERC‑20 token, the flow is simple on paper but involves several on‑chain steps:
- Connect a Web3 wallet (Metamask, Ledger, etc.) to the BoringDAO web UI.
- Send Bitcoin to the designated custodial address-this triggers a locked‑balance event on the Bitcoin network.
- The bridge’s smart contract mints an equivalent amount of oBTC on Ethereum.
- Pay the 0.2% minting fee plus Ethereum gas.
- Use oBTC in any DeFi protocol: lend on Aave, provide liquidity on Uniswap, or stake for yield.
- When you want to get your original Bitcoin back, redeem oBTC. The contract burns the token, releases the locked BTC, and charges another 0.2% fee.
Because the bridging process relies on smart contracts and a custodial vault, users must trust both the code and the entity managing the BTC lock.
Governance: The BOR DAO
All protocol upgrades, fee adjustments, and asset‑addition proposals are voted on by holding BOR (the governance token). The DAO uses a standard snapshot voting mechanism, allowing token‑weighted votes without gas costs for each ballot. However, the limited on‑chain activity and scarce community chatter suggest that governance participation has dwindled in recent months.
Comparison with Other Cross‑Chain Bridges
Bridge | Primary Asset Focus | Decentralization Model | Typical Fee | Active as of Oct2025 |
---|---|---|---|---|
BoringDAO | Bitcoin ↔ Ethereum | DAO‑governed, custodial vault | 0.2% + gas | Service paused / legacy mode |
Polygon Bridge | ERC‑20 & NFTs across Polygon/Ethereum | Hybrid (validators + contracts) | ~0.1% + gas | Fully active |
Thorchain | Multi‑asset (BTC, BNB, ETH, etc.) | Fully decentralized liquidity nodes | 0.3%-1% | Fully active |
Arbitrum Bridge | Ethereum Layer‑2 assets | Optimistic Rollup, smart‑contract based | ~0% (only gas) | Fully active |
The table shows that BoringDAO’s fee structure is competitive, but its narrow asset focus and apparent service pause put it at a disadvantage compared with broader, actively maintained bridges.
Current Status and Future Outlook
Recent updates on the official website have shifted tone from “bridge services” to a more playful “have fun” message, implying that the original tunneling functionality is either deprecated or in maintenance mode. No fresh code commits, audit reports, or community AMA sessions have appeared since early 2024, and trading volumes remain minuscule.
That said, the underlying idea-decentralized Bitcoin‑to‑Ethereum bridges-remains valuable. Other projects (e.g., Wormhole, RenVM) continue to innovate on the same premise, meaning the technical concepts pioneered by BoringDAO still influence the ecosystem.

Pros and Cons at a Glance
- Pros
- Low 0.2% fee makes it cheaper than many alternatives.
- DAO governance gives token holders a say in protocol evolution.
- Focused Bitcoin bridge simplifies the user journey for BTC holders.
- Cons
- Service appears paused; no clear roadmap for relaunch.
- Limited asset support-only Bitcoin (no ERC‑20, no other chains).
- Data inconsistencies across market trackers create pricing confusion.
- Custodial vault introduces a centralization risk despite DAO overlay.
How to Interact (If You Still Want To)
Even with limited activity, the smart contracts are still on‑chain. If you have a legacy oBTC balance, you can redeem it by following these steps:
- Visit the archived BoringDAO UI (URL listed on the project’s GitHub readme).
- Connect your Ethereum wallet and locate the “Redeem oBTC” button.
- Approve the transaction-this will burn your oBTC tokens.
- Wait for the Bitcoin vault to release the corresponding BTC to the address you specify.
Remember to factor in both the 0.2% redemption fee and the Ethereum gas cost. If you’re looking for fresh Bitcoin‑to‑Ethereum bridges, consider alternatives like RenBridge or Wormhole, which have active development teams and clearer support channels.
Key Takeaways
- BoringDAO introduced a DAO‑governed Bitcoin‑to‑Ethereum bridge called oBTC.
- The native BORING token serves as governance and fee‑payment utility.
- Market data is fragmented; trading activity is extremely low as of 2025.
- The project’s original services appear to be in legacy or paused mode.
- For active bridging, newer protocols offer broader asset support and stronger community backing.
Frequently Asked Questions
What does the BORING token actually do?
BORING (also referred to as BOR) is the governance token for BoringDAO. Holders can vote on protocol upgrades, fee adjustments, and which new assets are added to the bridge network. It also pays the 0.2% minting and redemption fees.
Can I still use the oBTC tunnel to move BTC to Ethereum?
The smart contracts still exist, but the official UI shows a “past services” notice. If you have existing oBTC tokens, you can redeem them manually via the archived interface. New minting of oBTC is effectively halted.
How does BoringDAO’s fee compare to other bridges?
At 0.2% plus gas, BoringDAO is cheaper than most multi‑asset bridges (which often charge 0.3%‑1%). However, additional network fees for Bitcoin transactions can push the total cost higher than fee‑only bridges like the Arbitrum Bridge.
Is BoringDAO considered secure?
The code was built on OpenZeppelin libraries, which are audited and widely used. The main risk lies in the custodial Bitcoin vault-if the vault operator is compromised, the locked BTC could be lost. The DAO governance adds a layer of decentralization, but activity has dwindled, reducing active oversight.
What are the alternatives if I want to bridge Bitcoin to DeFi?
Popular alternatives include RenVM, Wormhole, and Thorchain. They support multiple assets, have active development teams, and provide clearer documentation. Fees range from 0.1% to 1% depending on the chain and congestion.

Reading through the BoringDAO overview, I see the token’s utility is pretty tightly bound to the oBTC bridge. The 0.2% fee seems modest, but when you factor in Ethereum gas, the total cost can vary widely. It’s a decent solution for people looking to lock BTC on Ethereum, though the bridge’s liquidity depth is something to watch. Overall, it feels like a thoughtful design, albeit with the usual DeFi risks.

Anyone else think the whole “boring” branding is just a meme to attract cheap hype?

lol the bridge fee calc looks slick, but dont forget gas can turn that 0.2% into a pricey surprise. i’d double check the eth fees before minting.
