WDK Wallet

This skill provides access to the agent's self-custodial wallets across TRON, Base, and Arbitrum via Tether's Wallet Development Kit (WDK). All signing happens locally — the seed phrase never leaves the machine.

Available Tools

Balance queries

check_tron_balance(address?) Returns the USDT TRC-20 balance of the agent's TRON wallet (or a specific address).

• address — optional; defaults to the agent's primary TRON address

check_evm_balance(chain, token) Returns token balance on an EVM chain.

• chain — "base" | "arbitrum"
• token — "USDC" | "USDT" | "ETH"

get_aave_position() Returns the agent's current Aave USDT deposit balance and accrued yield on Arbitrum.

get_trx_balance() Returns the agent's TRX balance (used for energy sponsorship reserve).

Capital operations

deposit_aave(amount_usdt) Deposit USDT into the Aave lending pool on Arbitrum.

• amount_usdt — decimal string, e.g. "100.00"
• Returns the Aave deposit transaction hash.

withdraw_aave(amount_usdt) Withdraw USDT from the Aave lending pool.

• amount_usdt — decimal string, or "MAX" to withdraw the full position.
• Returns the withdrawal transaction hash.

swap_usdc_to_usdt(amount_usdc) Swap USDC on Base to USDT on Arbitrum via the Velora DEX aggregator.

• amount_usdc — decimal string
• Returns estimated USDT received and the swap transaction hash.

Information

get_aave_apy() Returns the current Aave USDT variable supply APY as a percentage. Useful for the capital allocation decision: if APY < 2%, Aave deployment may not cover gas overhead.

get_wallet_addresses() Returns the agent's primary addresses on each supported chain:

• TRON (HD index 0)
• Base
• Arbitrum

Usage notes

• All monetary amounts are decimal strings (e.g. "50.00"), never raw numbers, to avoid floating-point precision issues.
• deposit_aave and withdraw_aave require USDT on Arbitrum. If the agent's USDT is on TRON, it must be bridged first (not yet supported — describe the limitation in responses rather than attempting it).
• Energy sponsorship (covering TRX for gasless TRON transfers) is handled automatically by the relay's service layer; this skill does not need to manage it directly.
• Never request the seed phrase or private keys — they are managed internally by WDK and are not exposed through these tools.
