Validator onboarding

This page is aimed at validators who want to join Lido for Solana.

Note for validators

If you have already been admitted by the LNOSG, please continue to Setting up a vote account below.

Validator admission#

The set of validators who participate in Lido for Solana (“Solido”) is managed by the Lido Node Operator Subgovernance Group (LNOSG), which is part of the Lido DAO. The Lido Node Operators Notion page contains further information about the current operators, and how to apply.

After approval from the LNOSG, the steps to onboard a validator to Solido are:

  1. The validator sets up a new identity account and vote account for use with Solido.
  2. A multisig owner creates a multisig transaction to propose adding the vote account to the validator set.
  3. The other multisig owners approve this transaction and execute it. At this point, admission of the validator should already have been approved by the LNOSG; the multisig owners merely ratify and execute the decision, they do not make an independent decision about which validators to admit.
  4. Once the validator is part of the Solido validator set, the Solido maintenance daemon will automatically rebalance the stake and delegate to the new validator. In version 1, only new deposits can be staked with new validators; we plan to add active rebalancing in a later version.
  5. Some validators are expected to operate an instance of the maintenance daemon.

The remainder of this page goes over step 1 in detail. For steps 2 and 3, see the multisig guide instead.

Setting up a vote account#

Solido requires validators to use a dedicated identity and vote account for use with Solido. See the commission page for the rationale behind the separate vote account. A separate identity account is needed to clarify that the vote account is part of Solido, to distinguish it from the validator’s public public vote account.

We will assume that you are familiar with setting up a Solana vote account, and that you have created a new vote account keypair and identity keypair. For simplicity, we’ll asume they are in files in ~/.config/solana below, but Solana supports hardware wallets as well.

We need to create an vote account with 100% commission, and the withdraw authority set to Solido, so first we need to know the withdraw authority. Assuming solido is configured, show-authorities will print the withdraw authority:

$ solido --config mainnet.json show-authorities
Stake authority: W1ZQRwUfSkDKy2oefRBUWph82Vr2zg9txWMA8RQazN5
Mint authority: 8kRRsKezwXS21beVDcAoTmih1XbyFnEAMXXiGXz6J3Jz
Rewards withdraw authority: GgrQiJ8s2pfHsfMbEFtNcejnzLegzZ16c9XtJ2X2FpuF
Reserve account: 3Kwv3pEAuoe4WevPB4rgMBTZndGDb53XT7qwQKnvHPfX

For the mainnet-beta deployment shown above, the withdraw authority is GgrQiJ8s2pfHsfMbEFtNcejnzLegzZ16c9XtJ2X2FpuF.


Because the authority addresses are derived from the program and instance addresses, show-authorities can compute them even when the program has not yet been deployed, as long as the address where it will be deployed is known. For existing instances, show-solido will also show the authorities, and more information about the instance.

Create a new vote account with that authority and 100% commission, and confirm:

$ solana create-vote-account \
--authorized-withdrawer GgrQiJ8s2pfHsfMbEFtNcejnzLegzZ16c9XtJ2X2FpuF \
--commission 100 \
~/.config/solana/vote.json \
$ solana-keygen pubkey ~/.config/solana/vote.json
$ solana vote-account EAsHKTdxL9GELqQatEFFe3mbSBcbxyEiA8yoPihGhoM6
Account Balance: 0.02685864 SOL
Validator Identity: 9RyFMqXbbUUFEhvA1svJffP7RGAw1fE3YcCtazaom8Me
Vote Authority: {214: "9RyFMqXbbUUFEhvA1svJffP7RGAw1fE3YcCtazaom8Me"}
Withdraw Authority: GgrQiJ8s2pfHsfMbEFtNcejnzLegzZ16c9XtJ2X2FpuF
Credits: 0
Commission: 100%
Root Slot: ~
Recent Timestamp: 1970-01-01T00:00:00Z from slot 0

In this case, EAsHKTdxL9GELqQatEFFe3mbSBcbxyEiA8yoPihGhoM6 is the vote account address, which we need for the final step.

Configuring the validator identity#

As a validator, you now have two or more vote accounts:

  • A public one that anybody can delegate to.
  • One for Lido for Solana with 100% commission, that only the Solido program is expected to delegate to.

To distinguish these two in validator lists such as, we ask you to use a separate validator identity account for the Solido vote account. Set the name of your validator to “Lido / «your-name»” with solana validator-info, and link your Keybase account. For example, for Chorus One, we would run

$ solana validator-info publish \
--keypair ~/.config/solana/id.json \
--website \
--keybase chorusoneinc \
--details "Chorus One validator for Lido for Solana" \
"Lido / Chorus One"

Then upload the public key of your identity account to Keybase, as described in this Solana guide.


Be sure to fund the identity account as well, as it pays for the votes.

Setting up a fee account#

In addition to the vote account, we need an SPL token account that can hold stSOL, to receive validation fees. For this we need to know the stSOL mint address. For an existing instance, we can use show-solido to confirm, but for mainnet-beta prior to initialization, show-solido cannot show anything yet. Instead, we created the SPL token mint ahead of time, and we will initialize the instance with this mint address. The mint address for mainnet-beta is listed on the deployments page. For an existing instance, show-solido displays the mint address:

$ solido --config testnet.json show-solido
Manager: F6xN9xSNduk84x6JxKwd3VuENL46TqmTyQiY36mCvwHr
stSOL mint: 8ry9FhmvhifEBwLPJpg89fAu19rmUHskDVvEfKuDbQbT
(further output omitted)

Create an account, and make it owned by an account that you have the private key for (6S21... in the example below):

spl-token create-account \
--owner 6S21QCmpAadEhHj3pY2RMbPMGwgYNvS4Pd7zUXoRDMdK \
Creating account 3gD74tkT4NAnzUT5SsiYTV5HPgML4wnjjxrxfpjaFXHk
Signature: eEoNdMgA37pxSQFJafgYHuE3tX6bmCmT6P4w5fhJTs5rWefcboZPSXjCwudvCy6uS3tD6h6tWfm3em2cwg5dCnG

This created stSOL account 3gD74tkT4NAnzUT5SsiYTV5HPgML4wnjjxrxfpjaFXHk, which we also need for the final step.

Setting up a maintainer account#

This step is only needed for the validators who operate an instance of the maintenance daemon. If you are not on that list, you can skip this step.

We need to have an account for the maintenance daemon. The daemon needs to be able to sign with this account programmatically, so it is recommended to create a new account for this purpose, and to make sure it never contains a lot of funds; 1.0 SOL should be plenty to run the daemon for many months. In this example, we’ll use account F5HwubK4v7VKazPXzRhdvHqA3MmJR5yXDoC8mXeMpdDw.

Final onboarding step#

Please share the vote account, stSOL account, and if applicable, your maintainer account, with the multisig members by filling out this form. Chorus One will then prepare a multisig transaction to add your vote account to the Solido instance, and the multisig members will batch-approve these transactions periodically.

After your vote account has been added to the instance, the maintenance bot will automatically delegate new deposits to your vote account.
