Cryptographic memory layer for AI agents. Fast. Private. Verifiable on Solana.

---

Installation

pip install solvec

# With Solana verification (Phase 2)
pip install "solvec[solana]"

# With Shadow Drive (Phase 5)
pip install "solvec[shadow-drive]"

# Full install
pip install "solvec[all]"

---

Quick Start

from solvec import SolVec

sv = SolVec()
collection = sv.collection("agent-memory", dimensions=1536)

# Insert memories
collection.upsert([
    {"id": "mem_001", "values": embedding, "metadata": {"source": "conversation"}},
    {"id": "mem_002", "values": embedding2, "metadata": {"source": "document"}},
])

# Semantic search
response = collection.query(vector=query_embedding, top_k=5)
for match in response.matches:
    print(f"{match.id}: {match.score:.4f} — {match.metadata}")

---

Phase 4: Encryption

from solvec import SolVec, EncryptionConfig

sv = SolVec(
    encryption=EncryptionConfig(
        enabled=True,
        passphrase="your-secret-passphrase"
    )
)
collection = sv.collection("encrypted-memories", dimensions=1536)
# All vectors and metadata are encrypted at rest using AES-256-GCM

---

Phase 2: Solana Verification

from solvec import SolVec, SolanaConfig

sv = SolVec(
    solana=SolanaConfig(
        enabled=True,
        network="devnet",
        keypair="/path/to/keypair.json"
    )
)
collection = sv.collection("verified-memories", dimensions=1536)

# After upsert, Merkle root is posted to Solana asynchronously
collection.upsert([{"id": "mem_001", "values": embedding}])

# Verify integrity
result = collection.verify()
print(f"Tampered: {not result.verified}")

---

Phase 5: Shadow Drive

from solvec import SolVec, ShadowDriveConfig

sv = SolVec(
    shadow_drive=ShadowDriveConfig(
        enabled=True,
        keypair="/path/to/keypair.json",
        snapshot_interval=10,  # snapshot every 10 writes
    )
)
collection = sv.collection("persistent-memories", dimensions=1536)

---

Phase 6: Memory Inspector

from solvec import SolVec, InspectorQuery

sv = SolVec()
collection = sv.collection("agent-memory", dimensions=1536)

# Write some memories
collection.upsert([
    {"id": "mem_001", "values": embedding1, "metadata": {"type": "episodic"}},
    {"id": "mem_002", "values": embedding2, "metadata": {"type": "semantic"}},
])

# Get the inspector
inspector = collection.inspector()

# Fast collection stats
stats = inspector.stats()
print(f"Total: {stats.total_memories} memories")
print(f"Size: {stats.memory_usage_bytes} bytes")
print(f"Merkle root: {stats.current_merkle_root}")

# Filter memories
result = inspector.inspect(InspectorQuery(
    metadata_filter={"type": "episodic"},
    limit=20,
))
for record in result.memories:
    print(f"{record.id} — written at {record.written_at}ms")

# Get a single record
record = inspector.get("mem_001")
print(f"Vector dim: {len(record.vector)}")
print(f"Merkle root at write: {record.merkle_root_at_write}")

# Semantic search with full records
matches = inspector.search_with_records(query_vector, k=5)
for score, record in matches:
    print(f"{record.id}: {score:.4f}")

# Merkle history
history = inspector.merkle_history()
for entry in history:
    print(f"{entry.trigger} — {entry.memory_count_at_time} memories — {entry.root[:16]}...")

# Tamper detection
proof = inspector.verify()
print("All good" if proof["match"] else "TAMPERED!")
