For depositors
Vaults
One deposit, spread across Solana's lenders, split into two seats.
How a vault works
Where your USDC goes
A curator lends it out across five venues. The yield comes back into one vault and is split between Senior and Junior. A loss is split too, and it always hits Junior first.

Two ways in
Pick your seat
The same vault, the same venues. The two tranches differ only in who eats a loss first, and what they are paid for it.
Senior · protected
Paid first
- Junior takes any loss before you do.
- A steadier rate: part of the yield goes to Junior as the price of that protection.
- Out in minutes: a short delay each vault sets (3 minutes on today's vaults).
Junior · first loss
Paid more, loses first
- Earns its own share of the yield plus the premium Senior pays.
- Takes the first loss, up to everything it holds.
- A notice period each vault sets (30 minutes on today's vaults), and a withdrawal is paid only while the vault keeps its minimum Junior share (20 % today).

Running a vault
What a curator does, and what the program won't allow
Spreading USDC across lenders is easy. Deciding how much can sit with one borrower, and how much Junior that needs, is the work. Nothing the curator decides can step outside what the program enforces.
The curator
- 01
Picks from a screened menu
Each venue in Akashi's registry is tagged by who holds the deposit, who ultimately borrows, what the return depends on, and how fast money can leave.
- 02
Is checked against a limit book
Concentration per venue and per borrower, exit depth within a day and a week, and a stress budget that must fit inside Junior. Each departure is acknowledged on the record, with a reason.
- 03
Cannot move outside the program
The curator chooses within the floor, the caps and the delays below. The program decides whether a move is allowed.

The program
A minimum Junior share
Each vault sets one (20 % on today's vaults). A Senior deposit that would leave less Junior in front of it is refused.
A cap on every venue
Each venue has a maximum share of the vault; the program refuses any move above it.
Changes wait
Raising a limit, adding a venue or changing a role is announced on-chain and applies after the vault's delay (1 hour on today's vaults).
Only safety is instant
A guardian can pause the vault or lower limits at once. Nothing that adds risk is instant.

The board
Every stablecoin rate on Solana, graded
Discover lists 184 opportunities across 22 venues: lending, vaults, yield-bearing stablecoins, fixed yield and more, each with its live rate and Akashi’s risk grade next to it, with the reasons in plain language. Deposit from your own wallet straight to the venue; Akashi is never in the money path.

Across all three
Akashi is never in the money path
A vault deposit goes into the on-chain program; a Discover deposit goes straight to the venue. Akashi's servers only build the transaction you sign; they hold nothing.
FAQ
The questions that matter
Anything else? Open a vault and read its page: every rule it runs on is stated there.
What does Junior actually do?
Junior is the capital that stands in front. When the vault books a loss, it comes out of Junior's value first; Senior loses only once Junior is gone. For taking that seat, Junior earns its own share of the yield plus a premium Senior pays, and the thinner Junior is, the larger the premium. Junior is a bet on the curator's choices; it can lose everything it holds.
Who takes the loss if a venue is hacked?
Junior, first. If a venue the vault lends to fails, the vault marks that venue impaired, closes deposits, and books the loss against Junior. Senior can still withdraw. Only a loss larger than all of Junior reaches Senior. Nothing removes the risk of DeFi; the vault decides who carries it, in advance and in public.
Who decides where the money goes?
A curator, within rules the program enforces. The curator picks venues from a screened registry, sets each one's share, and acknowledges every departure from Akashi's limit book on the record. The program then holds the line: a venue's cap and maximum share, fresh values before any move, the Junior floor, and a delay on every change that raises risk.
Can I get out?
Yes. A withdrawal is a request your wallet signs, then a second transaction after the vault's delay: a few minutes for Senior (3 minutes on today's vaults), a notice period for Junior (30 minutes today). Junior is paid only while the vault keeps its minimum Junior share in front of Senior; if a payout would breach the floor, the rest of the request waits in the queue and keeps earning or absorbing losses until it can be funded.
Does Akashi hold my funds?
No. A vault deposit goes from your wallet into an on-chain program whose rules anyone can read, and the program lends it on to the venues. Akashi's servers hold no funds and no key that can spend yours; they only assemble transactions for you to sign. On the Discover board, deposits go straight from your wallet to the venue you chose.
What does it cost?
Nothing from Akashi. The vault program has no management or performance fee, and the Discover board takes no spread out of your yield. You pay Solana's transaction fees, and each venue's own economics apply inside it.
Is this live on mainnet?
Yes. The vault program runs on Solana mainnet with real USDC, and the vaults listed on this site are the live ones. The figures on this page are read from the chain in your browser; every rate shown is an expectation from today's source rates, never a result.
Where does the yield come from?
From the venues, not from Akashi: interest that borrowers pay on Jupiter Lend and Kamino, and the return on tokenised credit such as Maple's syrupUSDC, Hastra's PRIME and Huma's PST. The vault books what those positions earn and splits it between the tranches the way its contract says.
