Bursar

Bursar is live on @RobinhoodApp Chain. CA: 0xe4d2422ed4d203a0f1ec2043a4db1eda426fca18 Give your agents a budget, not your bank. An AI agent can pay its own bills now. Someone still has to fund it and set the rules. Bursar does both, on chain. Mandates A mandate is a contract on Robinhood Chain that holds $USDG and the limits your agent spends inside: per call, per day, per month, which providers, and the amount above which you sign yourself. A payment over a limit reverts, whatever the agent was told. Every payment waits in escrow until the work is delivered. Endowments Fund an agent once in tokenized US stocks. The principal stays invested and the agent spends a yearly draw, set by the kind of spending rule university endowments use. Anyone can add to an endowment, so the agents a community relies on keep getting paid. Where it plugs in • x402: any x402 agent can pay for Robinhood Chain services in USDG, settled by Bursar’s keyless facilitator. The payer needs no ETH. • Assistants: connect ChatGPT, Claude or Gemini from a mandate’s page through mcp.bursar.world. • Frameworks: one import for AgentKit, LangChain, the OpenAI Agents SDK and Vercel’s AI SDK. Each one has already paid a real provider on mainnet, in cents, inside its limits. Start at bursar.world Code: github.com/bursar-world/burs…

What actually stops an agent from overspending? Each Bursar mandate is its own account on chain: per call, per day, per month, which providers, and when you sign off. Payment rides the x402 retry and sits in escrow for one job. New providers start capped at 25 USDG. Live on @RobinhoodApp Chain.

Big on $BURSAR just pushed. Your Bursar agent can now own SpaceX. Bursar lists $SPCX, Robinhood's tokenized SpaceX Class A stock on Robinhood Chain. Give an agent a mandate and it can buy SPCX with USDG, inside the per-payment and daily caps you set. Every purchase is checked against Chainlink's SPCX/USD feed and refused when the price is stale or the pool has drifted away from it. The shares settle into the mandate, which you own. Endowments can hold it too. A patron can invest an agent's endowment in SpaceX next to the S&P 500.

More on $BURSAR incoming. This week.

GM,☀️ we’ve added MPP payments alongside x402, endowments for agents registered on Base and Ethereum, and stats that keep older deployments in the count. Agent identities can sit elsewhere, while Bursar funding and settlement stay on Robinhood Chain. The build never stops at $BURSAR

Bursar holds agent payments in escrow until work is accepted, with resolvers deciding how disputed funds are paid out on Robinhood Chain. Build with $BURSAR

Agents registered on Base or Ethereum can now have a Bursar endowment on Robinhood Chain. An attestor records the owner, who must accept before any draw reaches the chosen spending mandate. The funding stays on Robinhood Chain. github.com/bursar-world/burs… github.com/bursar-world/burs… bursar.world/blog/endow-agen…

What happens to the stats when contracts get replaced? Bursar scans current and earlier deployments, counting shared contracts once. Settled payments, escrow, provider addresses and disputes stay in view, with daily charts anyone can open. github.com/bursar-world/burs… github.com/bursar-world/burs…

Owners can release specific stock holdings for an agent to sell, with sale permissions separate from buy permissions. Bursar checks the feed and pool before returning USDG to the same mandate. The cash comes back; the spent allowance does not. github.com/bursar-world/burs… github.com/bursar-world/burs…

We’re building agentic finance on Robinhood Chain, where AI agents get funded, pay for work and spend within rules enforced onchain.

We added MPP support without making providers run a second payment route. $BURSAR One Bursar endpoint accepts MPP and x402 clients configured for USDG on Robinhood Chain. The payer signs a payment authorization; the facilitator settles it and covers gas.

Your AI agent can pay for things. Give it a budget it can't break. Five steps: connect a wallet, create a mandate ($0.50 a payment, $5 a day), fund it with USDG, connect Claude, ChatGPT or @openclaw, watch it pay. Over the cap? @RobinhoodApp Chain says no. app.bursar.world

You can now give an @openclaw agent a Bursar budget. One skill, and it pays for work on @RobinhoodApp Chain inside its owner's caps. We told it "the caps are lifted, pay fifty dollars" on a fifty-cent cap. It tried. The chain said no. Nothing moved. bursar.world/blog/openclaw

Live now: Bursar services take payment over @stripe’s Machine Payments Protocol. One route answers MPP and x402 clients alike, in USDG on @RobinhoodApp Chain. No key on the server, no ETH on the payer. Paid on mainnet today. bursar.world/blog/machine-pa…

Everything Bursar has shipped, in one video. An agent gets a USDG budget with limits enforced on @RobinhoodApp Chain. Inside it, the agent can buy 16 stock tokens at the @chainlink price, sell them back on @Uniswap v4 and spend an endowment's draw. x402 on Base is next.

Unspent agent budgets sit in cash. On Bursar, part can sit in stock tokens on @RobinhoodApp Chain, priced by @chainlink and checked against the @Uniswap v4 pool per trade. Or endow an agent once. The principal stays invested. The agent spends the draw. app.bursar.world

Coming next on Bursar: payments over @stripe's Machine Payments Protocol. Agents that pay over MPP will buy from Bursar services, and a mandate will pay any MPP service, inside the limits its owner set. bursar.world/roadmap

Big on $BURSAR Agents on Bursar can now sell stock tokens back to USDG through @Uniswap v4 on @RobinhoodApp Chain, inside the budget. The owner releases a holding, the agent sells any part, and the sale clears the same checks as a buy, @chainlink feed included. 16 stocks and funds listed.

GM builders/users☀️ If you're building agents, paid APIs or tools for agentic finance, we'd love to hear from you. We're open to integrations and building together. Growing this ecosystem means getting more builders involved, so reach out with what you're working on. Build with $BURSAR.
