Trust Wallet Agent Kit Introduces Onramps & Offramps

Trust Wallet AI agents could read crypto. Prices, risk signals, token metadata - all accessible through a single API.

Three weeks ago, they could act on it. Real swaps, real transfers, across 25+ chains.

Two weeks ago, they could run your strategy. DCA on a schedule, limit orders triggered by price.

This week, they can handle the fiat side of the journey too.

Trust Wallet Agent Kit now supports on-ramp and off-ramp - giving developers and AI agents programmatic access to Trust Wallet's licensed fiat infrastructure via CLI and MCP. The same providers already serving millions of Trust Wallet mobile users. The same self-custody model. A new client entry point.

What's new

Trust Wallet has always offered fiat on/off-ramp inside the mobile app through licensed third-party providers. That hasn't changed.

What's new is the surface. TWAK gives developers and AI agents a programmatic way to access that same infrastructure, via CLI and MCP, without building their own fiat integrations from scratch. The payments pipeline is unchanged. The client is new.

This matters for developers building agent-powered crypto apps. Getting fiat in and out has historically been the hardest part - licensing, KYC, provider integrations, payout rails. With TWAK's on/off-ramp, all of that is already handled. You're plugging into infrastructure that's been live in production, at scale, for millions of users.

How on-ramp works

The on-ramp flow lets an agent, or a user instructing an agent, query quotes for purchasing crypto with fiat, surface the best available rate, and generate a checkout link.

In practice, here's what happens:

The agent requests quotes for a fiat amount and target asset via the Trust Wallet gateway. The gateway returns offers from licensed third-party providers, the same ones already integrated with the Trust Wallet mobile app. The agent surfaces the best available option. A checkout URL is generated. The user opens it in a browser, completes KYC with the provider, and authorises the payment.

The provider delivers crypto directly to the user's self-custodial wallet address, auto-derived from the user's locally stored HD wallet, or supplied explicitly. TWAK never holds funds, never performs KYC, and never collects payment information. It transmits only what the mobile app would: fiat amount, currency code, asset ID, and destination address.

For developers, the on-ramp is a two-step CLI flow:

# Step 1: fetch and sort quotes — quotes[0] returns the best rate
twak onramp quote --amount 500 --asset c60 --currency USD

# Step 2: select the best quoteId and generate a checkout URL
twak onramp buy --quote-id <id> --asset c60

The agent fetches the quotes and surfaces the best rate. The user opens the checkout URL to complete the purchase directly with the provider.

How off-ramp works

The off-ramp flow is the mirror: an agent queries sell quotes for a crypto amount, target fiat currency, and payout method (bank transfer or card). The gateway returns offers from licensed providers. The agent surfaces the best rate. A checkout URL is generated.

The user opens it, completes KYC with the provider if required, and signs the outgoing crypto transfer from their own self-custodial wallet. The provider credits the agreed fiat amount to the user's bank account or card on its standard payout schedule — typically one to three business days for bank transfer.

Again, TWAK never takes custody of the crypto or the fiat payout. The source wallet address is auto-derived from the user's locally stored HD wallet, or supplied explicitly.

The off-ramp is a three-step flow:

# Step 1: fetch and sort sell quotes
twak onramp sell-quote --amount 1 --asset c60 --currency USD

# Step 2: select best quoteId — generates checkout URL; user completes KYC
# provider returns a deposit address
twak onramp sell --quote-id <id> --asset c60

# Step 3: broadcast the on-chain payout from the user's wallet
twak onramp sell-confirm --asset c60 --to <deposit-address> --amount 1

The user completes KYC with the provider via the checkout URL. The provider returns a deposit address. The final step broadcasts the on-chain transfer from the user's own self-custodial wallet — TWAK never holds the crypto.

What the full workflow looks like

Put it all together and an agent can now assist with the complete fiat-to-crypto-to-fiat journey:

# On-ramp (two-step): twak onramp quote --amount 500 --asset c60 --currency USD
twak onramp buy --quote-id <id> --asset c60 

# Automated DCA (USDC → ETH weekly): twak automate add --from c60_t0xA0b86991... --to c60 --amount 100 --interval 7d 

# Off-ramp (three-step): twak onramp sell-quote --amount 1 --asset c60 --currency USD 
twak onramp sell --quote-id <id> --asset c60
twak onramp sell-confirm --asset c60 --to <deposit-addr> --amount 1

The automation middle layer — DCA, limit orders, rebalancing — runs autonomously within the rules the user configures upfront. The fiat entry and exit points require the user at two moments: completing the checkout for on-ramp, and confirming the on-chain payout for off-ramp. The agent handles everything in between.

This is the design intentionally. The agent removes friction and does the research. The user stays in control of the fiat transactions.

Why self-custody still matters here

Fiat on/off-ramp is an area where many services require you to give up custody of your crypto - either holding it on behalf of a centralised platform, or routing it through an intermediary before converting.

TWAK's on/off-ramp works differently. Crypto is delivered directly to the user's self-custodial wallet on on-ramp. On off-ramp, the user signs the outgoing transfer from their own wallet. At no point does Trust Wallet or TWAK hold the assets.

The same principle that's always defined Trust Wallet - your keys, your crypto - applies here too.

What builders can do now

With on/off-ramp live in TWAK, developers can build agents that:

• Query and surface competitive fiat-to-crypto rates across multiple licensed providers

• Generate checkout links for purchases and sales, ready for user completion

• Combine fiat entry with automated strategy execution in a single agent workflow

• Support bank transfer and card payout on off-ramp

• Operate across the same 25+ chains TWAK already supports
