Blast

Blast is an Ethereum layer-2 network implemented as an EVM-compatible optimistic rollup. Its distinguishing design choice is native yield: rather than a 0% default interest rate as on other L2s, Blast documentation states a default rate of 4% for ETH and 5% for stablecoins, with the yield sourced from decentralized protocols and passed back to users automatically.

Technically, the chain is a fork of Optimism and op-geth (the OP Stack), and the project publishes its fork and node-deployment tooling openly. On Blast, ETH itself — not a wrapped or liquid-staking ERC-20 — rebases natively for externally owned accounts, while smart contracts can opt in. Bridged stablecoins are converted to USDB, Blast's auto-rebasing native stablecoin, which rebases automatically for both EOAs and smart contracts (contracts may opt out) and can be redeemed for DAI when bridging back to Ethereum. Blast attributes ETH yield to L1 staking (initially via Lido, made possible after Ethereum's Shanghai upgrade) and USDB yield to MakerDAO's on-chain T-Bill protocol, noting that the Blast community may later supplement or replace these providers.

A BLAST token exists and is tracked by market-data providers, with tokenomics listing a 100 billion total supply and a launchpool distribution of 5 million BLAST (0.01%).

Business model

Blast operates blockchain infrastructure: users bridge assets to the L2 and transact, paying gas fees. The documentation states that, unlike other L2s that retain gas-fee revenue, Blast programmatically returns net gas revenue to Dapps, which developers may keep or use to subsidize user gas costs. A native token (BLAST) is also in circulation.

Network gas fees, with net gas revenue redistributed to Dapps per the protocol design described in Blast's documentation.

Traction

Public GitHub repositories show community engagement: the protocol fork repository has 101 stars and 59 forks, and the node deployment repository has 81 stars and 35 forks. Market data lists a BLAST token price of $0.0002724 with a fully diluted valuation of roughly $27.24M and market cap of roughly $5.81M.
