+# Go SDK Implementation Guidelines for Solana AI Registries
+
+## Overview
+
+This document provides comprehensive implementation guidelines for the Go SDK (`github.com/svmai/registries`) for Solana AI Registries. The SDK provides Go developers with a complete toolkit for interacting with on-chain AI agent and MCP server registries, including payment flows and IDL-based type safety.

+package idl
+
+import (
+    _ "embed"
+    "encoding/json"
+)
+
+// Embedded IDL files using go:embed directive

+var agentRegistryIDL []byte
+
+//go:embed mcp_server_registry.json
+var mcpServerRegistryIDL []byte
+
+// IDL represents the structure of an Anchor IDL
+type IDL struct {
+    Version      string        `json:"version"`
+    Name         string        `json:"name"`
+    Instructions []Instruction `json:"instructions"`

+    Errors       []Error       `json:"errors"`
+    Constants    []Constant    `json:"constants"`
+}
+
+// LoadAgentRegistryIDL loads and parses the agent registry IDL
+func LoadAgentRegistryIDL() (*IDL, error) {
+    var idl IDL
+    if err := json.Unmarshal(agentRegistryIDL, &idl); err != nil {
+        return nil, fmt.Errorf("failed to unmarshal agent registry IDL: %w", err)
+    }
+    return &idl, nil
+}

+        return nil, fmt.Errorf("failed to unmarshal MCP server registry IDL: %w", err)
+    }
+    return &idl, nil
+}
+```
+
+## 3. Error Handling Guidelines
+
+### 3.1 Error Type Definitions
+
+**File:** `errors/errors.go`
+
+**Reference:** [Effective Go - Errors](https://golang.org/doc/effective_go#errors), [`rust/src/errors.rs`](../rust/src/errors.rs)
+
+```go
+package errors
+
+import (
+    "fmt"
+    "errors"
+)
+
+// RegistryError represents errors from the Solana AI Registries SDK
+type RegistryError struct {
+    Code    uint32
+    Message string
+    Cause   error
+}
+
+func (e *RegistryError) Error() string {
+    if e.Cause != nil {
+        return fmt.Sprintf("registry error %d: %s (caused by: %v)", e.Code, e.Message, e.Cause)
+    }
+    return fmt.Sprintf("registry error %d: %s", e.Code, e.Message)
+}
+
+func (e *RegistryError) Unwrap() error {
+    return e.Cause
+}
+
+// Common error constructors
+func NewInvalidAgentIDError(cause error) *RegistryError {
+    return &RegistryError{
+        Code:    1001,
+        Message: "agent ID length is invalid (empty or exceeds max)",
+        Cause:   cause,
+    }
+}
+
+func NewInsufficientFundsError(cause error) *RegistryError {
+    return &RegistryError{
+        Code:    1002,
+        Message: "insufficient funds for transaction",
+        Cause:   cause,
+    }
+}
+
+// Error type checking functions
+func IsInvalidAgentIDError(err error) bool {
+    var regErr *RegistryError
+    return errors.As(err, &regErr) && regErr.Code == 1001
+}
+
+func IsInsufficientFundsError(err error) bool {
+    var regErr *RegistryError
+    return errors.As(err, &regErr) && regErr.Code == 1002
+}
+```
+
+### 3.2 Error Handling Patterns
+
+**Best Practices:**
+1. **Wrap errors with context:** Always provide context when wrapping errors
+2. **Use typed errors:** Create specific error types for different failure modes
+3. **Handle timeouts:** Implement proper timeout handling for RPC calls
+4. **Retry logic:** Implement exponential backoff for transient failures
+5. **Logging:** Log errors with appropriate levels and context
+
+**Example Implementation:**
+```go
+// WithRetry implements exponential backoff retry logic
+func WithRetry(ctx context.Context, maxRetries int, operation func() error) error {
+    var lastErr error
+    for i := 0; i < maxRetries; i++ {
+        if err := operation(); err != nil {
+            lastErr = err
+            if isRetryableError(err) {
+                backoff := time.Duration(i) * time.Second
+                select {
+                case <-ctx.Done():
+                    return ctx.Err()
+                case <-time.After(backoff):
+                    continue
+                }
+            }
+            return err
+        }
+        return nil
+    }
+    return fmt.Errorf("operation failed after %d retries: %w", maxRetries, lastErr)
+}
+```
+
+## 4. Testing Requirements
+
+### 4.1 Unit Tests
+
+**Coverage Requirement:** >90% code coverage using `go test -cover`
+
+**Test Structure:**
+```go
+func TestAgent_Register(t *testing.T) {
+    tests := []struct {
+        name    string
+        card    Card
+        wantErr bool
+        errType error
+    }{
+        {
+            name: "valid agent registration",
+            card: Card{
+                ID:          "test-agent-001",
+                Name:        "Test Agent",
+                Description: "A test agent for unit testing",
+                Version:     "1.0.0",
+            },
+            wantErr: false,
+        },
+        {
+            name: "invalid agent ID - too long",
+            card: Card{
+                ID:          strings.Repeat("a", 65), // exceeds max length
+                Name:        "Test Agent",
+                Description: "A test agent for unit testing",
+                Version:     "1.0.0",
+            },
+            wantErr: true,
+            errType: &RegistryError{Code: 1001},
+        },
+    }
+
+    for _, tt := range tests {
+        t.Run(tt.name, func(t *testing.T) {
+            // Test implementation
+        })
+    }
+}
+```
+
+### 4.2 Integration Tests
+
+**File:** `tests/integration_test.go`
+
+**Acceptance Criteria:**
+- **All tests pass:** Integration tests must run successfully against Solana devnet
+- **Coverage >90%:** Use `go test -cover` to verify code coverage exceeds 90%
+- **Output reproducible:** Running the tests multiple times yields the same results
+
+**Reference:** [`docs/SDK_ROADMAP_DETAILED.md`](SDK_ROADMAP_DETAILED.md:93)
+
+**Test Command:**
+```bash
+go test ./... -run TestIntegration -tags=devnet
+```
+
+**Example Integration Test:**
+```go
+//go:build devnet
+// +build devnet
+
+package tests
+
+import (
+    "context"
+    "testing"
+    "time"
+
+    "github.com/stretchr/testify/require"
+    "github.com/svmai/registries/agent"
+    "github.com/svmai/registries/client"
+)
+
+func TestIntegration_AgentLifecycle(t *testing.T) {
+    if testing.Short() {
+        t.Skip("skipping integration test in short mode")
+    }
+
+    ctx, cancel := context.WithTimeout(context.Background(), 30*time.Second)
+    defer cancel()
+
+    // Setup client
+    cfg := &client.Config{
+        RPCEndpoint: "https://api.devnet.solana.com",
+        Commitment:  rpc.CommitmentFinalized,
+        Timeout:     10 * time.Second,
+    }
+    client, err := client.NewClient(cfg)
+    require.NoError(t, err)
+
+    // Test agent registration
+    card := agent.Card{
+        ID:          "integration-test-agent",
+        Name:        "Integration Test Agent",
+        Description: "Agent for integration testing",
+        Version:     "1.0.0",
+    }
+
+    // Register agent
+    sig, err := agent.Register(ctx, client, testSigner, card)
+    require.NoError(t, err)
+    require.NotEmpty(t, sig)
+
+    // Verify registration
+    retrievedCard, err := agent.Get(ctx, client, card.ID)
+    require.NoError(t, err)
+    require.Equal(t, card.ID, retrievedCard.ID)
+    require.Equal(t, card.Name, retrievedCard.Name)
+
+    // Update agent
+    card.Description = "Updated description"
+    sig, err = agent.Update(ctx, client, testSigner, card)
+    require.NoError(t, err)
+    require.NotEmpty(t, sig)
+
+    // Verify update
+    retrievedCard, err = agent.Get(ctx, client, card.ID)
+    require.NoError(t, err)
+    require.Equal(t, "Updated description", retrievedCard.Description)
+
+    // Delete agent
+    sig, err = agent.Delete(ctx, client, testSigner, card.ID)
+    require.NoError(t, err)
+    require.NotEmpty(t, sig)
+
+    // Verify deletion
+    _, err = agent.Get(ctx, client, card.ID)
+    require.Error(t, err)
+    require.True(t, errors.Is(err, &RegistryError{Code: 404}))
+}
+```
+
+### 4.3 Performance Tests
+
+**File:** `tests/performance_test.go`
+
+**Benchmarks:**
+```go
+func BenchmarkAgent_Register(b *testing.B) {
+    client := setupTestClient()
+    card := agent.Card{
+        ID:          "benchmark-agent",
+        Name:        "Benchmark Agent",
+        Description: "Agent for benchmarking",
+        Version:     "1.0.0",
+    }
+
+    b.ResetTimer()
+    for i := 0; i < b.N; i++ {
+        _, err := agent.Register(context.Background(), client, testSigner, card)
+        if err != nil {
+            b.Fatal(err)
+        }
+    }

+
+**Example Code Style:**
+```go
+// RegisterAgent registers a new AI agent in the Solana registry.
+//
+// The agent card contains all necessary information for registry entry
+// including ID, name, description, and service endpoints. The signer
+// must be authorized to create registry entries.
+//
+// Returns the transaction signature on success or an error on failure.
+// Common errors include invalid agent data, insufficient funds, and
+// network connectivity issues.
+func RegisterAgent(ctx context.Context, client *Client, signer PrivateKey, card AgentCard) (*Signature, error) {
+    if err := validateAgentCard(card); err != nil {
+        return nil, fmt.Errorf("invalid agent card: %w", err)
+    }
+
+    tx, err := buildRegisterTransaction(card, signer.PublicKey())
+    if err != nil {
+        return nil, fmt.Errorf("failed to build transaction: %w", err)
+    }
+
+    sig, err := client.SendTransaction(ctx, tx, signer)
+    if err != nil {
