Project Description

OneVault lets Telegram’s community earn real EVM ecosystem yields without leaving telegram ecosystem. Users deposit USDT into a TON-native vault; the vault wraps it as usdt0 (OFT), bridges funds over LayerZero to Arbitrum (or any EVM chain), and auto-stakes the stablecoins across Aave and complementary protocols. An embedded AI agent reallocates capital to optimise APY and control risk (in future)

How it's Made

Built around a TON-native oApp written in FunC (and for R&D stage i learned FunC++ framework from LayerZero’s team), the vault has no official docs—I reverse-engineered the LZ codebases to make it work. Once the oApp receives a user’s deposit, it wraps the funds as usdt0 (OFT) and bridges them through LayerZero to Ethereum, where an EVM solidity contract auto-stakes the USDT in Aave as MVP.

in the future: i plan to deploy several vaults with ascending risk profiles— 1 Low risk (5-7 % APY): USDT lending only 2 Moderate risk (7-15 %): lending + synthetic stablecoins + stableswap AMMs 3 High risk (25-100 %): adds yield-derivative protocols like Pendle

Every vault is overseen by an AI agent that continually rebalances positions across a whitelisted set of protocols, so it can never steal funds; at worst it allocates capital sub-optimally.

all in all: This architecture delivers safety, decentralisation, and one-click access to tailored yield strategies for TON and Telegram’s massive user base.
