HashPort Wallet now allows its users to connect to Kiln’s DeFi infrastructure
< BlogHashPort Wallet, serving more than 1 million users in Japan, began to connect to yield strategies powered by Kiln DeFi, marking one of the first launches of this kind in Japan.
120M+ Japanese are stuck in near-zero-yield accounts
Japanese savings accounts pay near-zero interest, and government bonds offer minimal returns. While digital assets have strong adoption in Japan, most users face limited options: risky active trading or letting funds sit idle.
To earn yield, Japanese users would need to navigate external platforms, move funds across multiple interfaces, and monitor positions separately – making the experience inconvenient enough that most simply don't bother.
The solution: seamless connection from the wallet to yield opportunities
With Kiln's vault infrastructure and reporting capabilities, wallets like HashPort Wallet can now provide a seamless connection to yield opportunities provided via Kiln, without developing the solution in-house; users can connect from the wallet to Kiln’s widget to deposit and monitor positions in real-time.
HashPort users can access two strategies through Kiln's vault infrastructure:
- Lend AAVE v3 USDC on Base – Stablecoin lending with predictable returns
- Lend AAVE v3 cbBTC on Base - Bitcoin-based strategies generating returns on BTC holdings
Both use Aave, a battle-tested protocol with proven security, deep liquidity, and over $30 billion in total value locked across chains.
Kiln's onchain infrastructure track record
In 2025, Kiln crossed over $18 billion in assets delegated across major blockchains and powers earning features for the world's largest retail wallets: Trust Wallet, Ledger, Safe, and Bitpanda.
HashPort is providing a seamless connection to this same institutional-grade infrastructure for Japan's retail market.
