Rules your family can rely on, kept by code instead of a firm
Trellis replaces the usual estate-planning paperwork with a Solana program. You set the rules once, and the program checks them on every transaction.
Your heirs, written into the program
Name up to 10 people. The vault pays them and no one else. Every new name waits 48 hours before it can receive anything. When ownership has to change hands, guardians open a 72-hour handover that you can cancel before it completes.
- Withdrawals only go to people on your list
- A 48-hour wait on every new name
- Guardian-led handover of ownership, with a 72-hour wait
Family
No single key moves serious money
Appoint up to 5 guardians: family, a lawyer, an accountant. The owner can never be one. A withdrawal above the daily limit waits on-chain until a guardian signs. Skipping the wait for a new name takes 2 different guardians.
- Up to 5 guardians per vault
- A guardian signs every withdrawal above the limit
- 2 signatures to skip the wait for a new name
250 USDC to Ana
ApprovedAbove the daily limit, so it needed a guardian.
- Ana, daughterSigned
- Family lawyerNot needed
- AccountantNot needed
- You, the ownerCan't approve
A hard ceiling on every day
Set a daily USDC limit. The Solana program enforces it, not a server, and resets it every UTC day. A withdrawal that would cross the line doesn't fail silently. It becomes a request for a guardian to approve.
- Caps how fast a vault can be drained
- Resets automatically at 00:00 UTC
- Anything above the limit goes to a guardian
15 USDC left. Resets in 6 h 40 min.
Sending 40 USDC to Deniz is above today's limit, so it will wait for a guardian.
Fast, cheap, and always on
Trellis runs on Solana, so transfers settle in well under a second for a fraction of a cent. The vault account is rent-exempt, so it stays on-chain with no upkeep, and there's no Trellis server that has to be running.
- Settles in about 400 ms
- Fees of a fraction of a cent
- Rent paid once, when the vault is created
