@base Batches 004 is out, here's a summary if you don't have time to go through it:
🟦 Payments and Settlement
Saturday (
@SaturdayBank)
Traditional crypto cards spend stables and the merchant gets fiat. Saturday reverses the settlement: the customer pays with a normal Visa or Mastercard, and the merchant receives USDC on Base.
Conta (
@contavcbr)
Brazilian banks can debit salary on arrival to cover debt. Conta is a reais account on PIX where that money lands in a wallet only the user can move, so they decide what to pay and when.
🟦 Credit and Financing
Renn Finance (
@RennFinance)
DeFi loans get liquidated when price moves. Renn is fixed-term borrowing against crypto or tokenized stocks, no liquidation before maturity. The borrower pays a fixed rate for that. If the collateral ends below the amount lent, the lender eats the gap.
BitRepo (
@bitrepo_xyz)
BitRepo gives bitcoin a yield without selling it. It borrows stables against the BTC and lends that cash into short-term business credit, so the holder earns the spread. The company default risk stays with them.
🟦 Trading Markets
Tribeca (
@Tribeca_xyz)
Tribeca is an onchain replacement for a stock exchange: a CLOB on Base for 24/7 trading of tokenized stocks, perps, and options.
Greek.fi (
@GreekDotFi)
Most onchain options sit inside a closed venue. Greek turns options and the seller's collateral receipt into ERC-20s, so idle tokens can earn by selling calls, hedge with puts, or take leverage, and the locked collateral can be reused elsewhere.
🟦 Consumer Investing
Grow (
@get_grow_app)
Local-currency investing account, not a dollar neobank. Deposit a supported currency 1:1, earn yield on that currency, and buy US stocks, ETFs, or crypto from the same account without converting to USD first.
🟦 Agents and AI commerce
Mercatus (
@mercatus_ai)
Model APIs post a rate card, not a market price. Mercatus is an exchange for inference: pay per token now, or buy and sell next month's usage, so compute has a public price.
Flovia (
@Flovia402)
Flovia is Google Analytics for people who sell APIs and MCPs, but for agent customers. It shows the path agents take inside Claude or Codex: discover, choose you or a competitor, call, pay, finish. Sellers normally never see that funnel. Flovia marks where agents drop off and what to change so the API gets picked and paid.
🟦 FX
LEDiG (
@LEDiG_Tech)
Companies that get paid in stablecoins and pay suppliers in emerging-market currency have no onchain way to lock that FX. LEDiG is the hedging and liquidity layer for that flow, so the rate is fixed before the bill is due.
