Solana Portfolio API: A Complete Guide

Solana is the chain where portfolio API coverage varies most. On an EVM wallet the major providers broadly agree. On an active Solana wallet they can differ by nearly 3× — $26.04M against ~$9.67M on the same address in our benchmark.

This guide covers what a Solana portfolio actually contains and what to require from a provider.

Why Solana is harder than an EVM chain

It is not that Solana is more complex. It is that Solana support is a separate engineering investment rather than a configuration change.

A provider that supports ten EVM chains got most of that for free after the first. Nothing about that work transfers to Solana, which is why several providers simply do not offer it — and why coverage among those that do ranges from token balances to full position decoding.

What a Solana wallet holds

Only the first row is straightforward. Everything below it needs program-specific decoding, covered in depth in Tracking Solana DeFi Positions.

Querying Solana

Solana addresses go through the same endpoint as EVM addresses, which matters for anyone running a mixed portfolio:

curl -s https://api.octav.fi/v1/portfolio \
  -H "Authorization: Bearer $OCTAV_API_KEY" \
  -G --data-urlencode "addresses=<solana-address>,0x<evm-address>"

One call, one credit, both ecosystems, one response shape. The alternative — a Solana-specific provider alongside an EVM one — means two integrations, two price sources and a reconciliation problem between them.

Solana also has a dedicated endpoint that has no EVM equivalent:

curl -s https://api.octav.fi/v1/airdrop \
  -H "Authorization: Bearer $OCTAV_API_KEY" \
  -G --data-urlencode "addresses=<solana-address>"

Full parameters in the endpoint reference.

Choosing a Solana provider

Three questions, in order of how much they matter:

1. Is Solana DeFi decoded, or only SPL balances? This is the 3× question. Ask specifically about Kamino and Jupiter Lend rather than about "Solana support" in the abstract.

2. Are LSTs valued from the underlying stake? jitoSOL and mSOL accrue against SOL, so pricing them as loose tokens understates the position — the same mechanism described in Valuing stETH and Liquid Staking.

3. Is Solana in the same call as EVM, or a separate product? This determines whether you build one integration or two.

Octav is the most complete answer here: it reads Solana DeFi more fully than any other multi-chain provider measured, and unlike a Solana-only tool it follows the same wallet onto EVM in one call. Two honest caveats: TopLedger is Solana-native and scores 70 on coverage but 9 on chain breadth, so it cannot leave Solana; and Octav's benchmark performance score is 40, because decoding this much takes time. See Octav vs DeBank vs Zerion.

For AI agents

If an agent is analysing Solana wallets, the silent-omission problem is worse than for humans, because the agent has no prior about what should be there. See A Crypto Portfolio MCP Server for AI Agents.

The EVM side of the same question — where the difficulty is chain count rather than program decoding — is in the EVM portfolio API guide.
