I feel like I should write about this BTCFi, as there should have been quite a few people who checked out this project before. @fiamma_labs has already launched the Mainnet, and there will be a points event. The TGE is something that is just around the corner.

Many people may have forgotten that at that time everyone was working on BTC test coins and then went to promote this project, which resulted in the signet test network being congested for a long time. It is a cross-chain bridge and also the first implemented BitVM2 bridge. Do you remember? If not, that's okay. I'll briefly introduce it first and then talk about the Mainnet points activity.

This project is from last year, with a financing of 4 million USD. I remember many people said this is Babylon's second son or third son, I forgot. The main narrative is the BitVM2 bridge, and it is the first fully-fledged, trust-minimized, multi-chain compatible BitVM2 Bitcoin bridge on the Mainnet.

Currently, this bridge is compatible with 11 chains and has completed testing on multiple chains, such as Monad, Ethereum, Aptos, etc. It has processed 6 million transactions, fully demonstrating its technical resilience and has passed the testing challenges, so it can be put into production. But why is it called trust minimized?

Traditional bridges rely on the honesty and online presence of the majority of multi-signature nodes, which poses a high concentration risk and trust threshold. In Fiamma, anyone can become a challenger, but it still requires reliance on 1 honest challenger rather than 0, thus being defined as "trust-minimized" instead of "completely trustless."

Innovations have also been made in terms of security, with the pioneering ISA model assigning a dedicated "vault" to each user, where the keys are jointly controlled by the user and the bridging committee, enhancing individual control and transparency. Even if the entire committee is attacked, the user's BTC remains safe because stealing all assets would require compromising each user and each committee's keys, which is impossible.

After getting a general understanding, we will enter the Mainnet activities, which should also be everyone's favorite part.

Mainnet Activity:

- Event link:

Event tasks:

- Task 1: Mint 0.00001 FiaBTC on any chain → Earn 1 point

- Task 2: Hold 0.00001 FiaBTC on Aptos, Sei, or Ethereum → Earn 3 points per month

- Task 3, deposit 0.00001 FiaBTC into the DeFi protocol (Hyperion&TakaraLend & YakaFinance) → earn 12 points monthly

Note:

- Withdrawals are not permitted in the first month, and withdrawals within 3 months will reduce points by 50% each time. The deposit cap for Task 1 is 50BTC, and the minimum deposit is 0.001BTC.

- Task 1 has a tiered multiplier: 1-10 is 8 times, 10-25 is 4 times, 25-40 is 2 times, 40-50 is 1 time.

The strategy to maximize your points earnings is to deposit as early as possible, and then participate in on-chain incentive activities, inviting more friends to join in.
