# Blast Network Stats: Native Yield, Activity and Gas

> Blast stats by day: native yield on ETH and USDB balances, the bridge holdings behind it, transactions, active addresses and the gas fees apps claim back.

**Question:** How busy is Blast, what yield do ETH and USDB balances earn there and how much gas have apps claimed back?

- Kind: Dashboard in Voltfin Vantage
- Topic: [Layer 2s](https://voltfincrypto.com/topics/layer-2)
- Chains: Blast, Ethereum
- Status: Planned. The data is not published yet, so this page states no figure; each figure will open its receipt when it is.

Blast is an Ethereum layer 2 built on the OP Stack whose balances earn yield on their own. ETH held on Blast and USDB, the stablecoin that dollar stablecoins become when bridged in, rebase upward as the assets behind them in Blast's bridge earn on Ethereum. This dashboard measures that yield from the rebasing contracts, beside the chain's daily transactions, active addresses and gas.

Blast also shares gas with the apps that generate it. A contract can opt in to claim the gas fees its transactions paid, and the share it may claim grows the longer the gas matures. The dashboard follows those claims and how much was forfeited by claiming early.

Yield and claims are read from Blast's predeploy contracts and its bridge on Ethereum, so every rate is a change between two pinned blocks and every claim is a transaction.

## Blueprint

### Native yield

What ETH and USDB balances on Blast earn, with the bridge holdings behind that yield.

- **ETH yield, 30 days** (%): The annualized change in Blast's ETH share price over the last 30 days, between two pinned blocks.
- **USDB yield, 30 days** (%): The annualized change in USDB's share price over the last 30 days, between two pinned blocks.
- **USDB supply** (USDB): USDB totalSupply() on Blast at the latest day-end block.
- **ETH behind Blast's bridge** (ETH): ETH held by Blast's bridge and yield managers on Ethereum at the latest day-end block, the base the ETH yield is earned on.
- **ETH and USDB yield by week** (%): Weekly realized yield of ETH and USDB balances on Blast over the selected period.

### Activity and gas claims

Transactions, active addresses and the gas fees apps claim back.

- **Transactions, latest day** (count): Transactions in Blast blocks on the latest complete UTC day, leaving out the L1 attributes deposit that opens each block.
- **Active addresses, latest day** (count): Distinct addresses that sent at least one transaction on Blast on the latest complete UTC day.
- **Gas claimed by day** (ETH): Gas fees claimed by contracts each day, with the part forfeited by claiming before the gas matured.
- **Contracts by gas claimed**: The contracts that claimed the most gas over the selected period, with their claims, average claim rate and yield mode where readable.

Filters: Period (Last month, quarter or year).

## How it will be measured

- ETH and USDB yield is the change in each rebasing contract's share price between two pinned day-end blocks, annualized, so the rate is what balances actually earned.
- Bridge holdings are the ETH and stablecoin positions of Blast's bridge and yield manager contracts on Ethereum at day-end blocks, the base the yield is earned on.
- Gas claims are read from calls to the Blast predeploy: the gas each contract claimed, the claim rate it received and the part left with the chain.
- Transactions and active addresses are counted per UTC day from Blast blocks, leaving out the L1 attributes deposit that opens each block.
- Every figure names its Blast or Ethereum block and the read behind it.

## Data it needs

- `yield_rates_daily` (to build): Supply rates, staking yields and vault share-price growth per pool and vault per day, in one comparable table.
- `token_supply_daily` (to build): Total supply of each registry token on each chain at day end: wrapped BTC, liquid staking tokens, tokenized assets and other tracked tokens.
- `bridge_flows_daily` (to build): Deposits into and withdrawals out of canonical and major third-party bridges by chain, token and day, plus escrow balances at day end.
- `chain_activity_daily` (to build): Transactions, active sending addresses, new addresses, contracts created and gas used on each chain per day, counted from blocks and transactions.
- `chain_fees_daily` (to build): Fees paid per chain per day in the native token: base fee and priority fee percentiles, total fees, and the share burned where the chain burns fees.
- `native_prices_daily` (to build): Reference prices of major assets read from on-chain oracle feeds (Chainlink latestRoundData) at each day's last block, with each round's update time.

## Questions

### How does Blast native yield work?

ETH bridged to Blast is put to work in staking on Ethereum, and dollar stablecoins bridged in are held in yield-bearing positions there. Blast passes the earnings to balances on the chain: ETH and USDB held by wallets rebase upward, so a balance grows without any claim.

### Do smart contracts on Blast earn yield?

Contracts choose a yield mode for their ETH and for their USDB and WETH: automatic, claimable or void. Automatic balances rebase, claimable yield is collected by the contract itself and void earns nothing. The dashboard shows how much is held under each mode where the contract's configuration can be read.

### What is Blast gas revenue sharing?

Blast lets a contract claim the gas fees its transactions paid. Claimable gas matures over time: claiming early returns a smaller share and leaves the rest with the chain, while waiting allows a fuller claim. The dashboard shows claims by day and by contract.

### What is USDB?

USDB is Blast's native dollar stablecoin. Dollar stablecoins bridged to Blast become USDB, the assets behind it are held in yield-bearing positions on Ethereum and USDB balances rebase as that yield arrives. The dashboard reads its supply and its rate.

### Is the Blast yield rate fixed?

No. It follows what the assets behind it earn on Ethereum, net of what Blast keeps, and it moves with staking rewards and savings rates. The dashboard reports the rate realized between pinned blocks rather than an advertised one.

## Glossary

- **Rebasing**: A token balance that grows on its own as yield accrues, instead of the holder receiving a separate payment.
- **Yield mode**: A contract's setting on Blast that decides whether its balance rebases automatically, accrues claimable yield or earns nothing.
- **Claimable gas**: Gas fees a contract has earned under Blast's revenue sharing but not yet claimed; the share it can claim grows as the gas matures.
